5.91/22.34 U.S. NAVY BAROMETER. Highest quality World War II ship’s pilot house barometer made for the U.S. Navy by the highly respected scientific instrument making firm of “Friez, Baltimore” as indicated on the bottom of the silvered brass dial. The 4 ¾ inch diameter dial indicates “PRESSURE Inches of Mercury, Compensated, BuShips (N) 21437” and is dated “(19)41.” “Compensated” means this precision instrument is adjusted for temperature error. The finely calibrated dial indicates atmospheric pressure in inches of mercury from 27.7 to 31.3 in 2/100th increments marked by tenths. It is housed under glass in its original black Bakelite case made by the General Electric Corp. with iconic GE logo with classic bulkhead mount on a flange measuring 6 ½ inches in diameter and 2 ¾ inches deep. Guaranteed to be functional and highly accurate. SOLD

The dual bellows system employed in this barometer (as opposed to single bellows found in the vast majority of barometers) assures a positive, instantaneous reading. The fine rack and pinion linkage coupling the movement to the indicator needle also provides a more accurate direct reading. This is a much higher quality instrument than the average domestic barometer.

22.33 RARE AMERICAN STICK BAROMETER! Extremely rare sailing ship barometer made by the pioneer nautical American makers, “E & GW BLUNT, NEW YORK” as precisely-engraved on the ivory register. Truly an incredible find! This classic old fashioned ship’s gimbaled barometer is made entirely of rich rosewood with ivory scales and all brass hardware. Distinctively American, its simple, slim design is elegant yet functional. The registers (scales) are beautifully-engraved. The left scale exhibits the weather indications “FAIR, CHANGE, RAIN.” On the right the scale is calibrated from 27 to 31 inches divided by tenths. A sliding vernier, activated by an ivory rack and pinion knob just below, is divided from 1 – 10 providing a precise readout to one 1/100th of an inch. The register is overlaid by its original old wavy glass retained with rosewood moldings. The mid-body of this instrument has the original brass gimbal which pivots within the barometer body in ivory grommets. The gimbal ring fits nicely into the solid brass yoke attached to a turned rosewood mount, allowing the barometer to swing properly in a seaway. Below the gimbal is the mercury thermometer with ivory scale marked in single degrees Fahrenheit from 18 to 108 F. Perhaps the most unusual aspect of this stick barometer is its innovative open cistern – a real departure from contemporary English and French barometers of the time, and evidence of the Blunt brothers’ cutting edge manufactory. The open cistern is protected by old wavy glass in keeping with the register. The compartment is backed by an ivory slab engraved “PATENT MARINE.” It contains the original hand-blown glass tube protected by two silvered brass covers. This simple but effective arrangement is similar to the “J” tubes used in terrestrial mercury wall barometers of the era. Despite its relative simplicity compared with English Victorian barometers of its age, this working ship’s instrument has a lovely pediment at the top and a sculpted, curvaceous cistern cover on the bottom. The entire instrument is in a remarkable state of original preservation considering it is at least 175 years old! It measures 41 inches high overall and 4 inches wide at the widest. It projects 7 inches outward from the bulkhead as mounted. Shipped without mercury. However arrangements can be made to fill the instrument and make it fully functional and accurate. This is certainly a Smithsonian candidate, if not already in that collection. 2887 Back to Top

The sibling partnership of Edmund and George William Blunt was formed in 1824 in New York under the name E. & G. W. Blunt. They were sons of Edmund March Blunt, famous publisher of “Blunt’s Nautical Almanac” of Newburyport, Massachusetts. Following a disastrous fire in 1811, the elder Blunt moved to New York City, where he continued his publishing. According to M.V. Brewington in “The Peabody Museum Collection of Navigating Instruments”…”The firm was possibly the most progressive in the United States, thanks perhaps to George joining the U.S. Coast Survey.” By 1833 they were the American agents for the foremost British chronometer makers. In 1836 they set up their own astronomical observatory in Brooklyn. By 1850 they were publishing a nautical almanac of their own and had agents in 20 East Coast and Gulf cities. In 1856 they completed a dividing engine on George’s design. They had many other accomplishments in the nautical realm. Edmund died shortly after the Civil War and George retired a year later. The firm sold out to John Bliss & Co., in 1871. George died in 1878.

5.35 /22.32 U.S. NAVY BAROMETER. Outstanding World War II era warship’s pilot house barometer made by the “Taylor Instrument Companies, Rochester, N.Y. Tycos” as signed on the bottom of the silvered brass dial. It is boldly marked “U.S. NAVY” just above. The scale reads in inches of mercury atmospheric pressure from 27.7 to 31.3 inches calibrated in 2/100th increments marked in tenths. The mid-point is marked with a traditional fleur-de-lis. The open face dial showcases the high quality, complex movement within. Just above the opening it is marked “MOVEMENT COMPENSATED FOR TEMPERATURE.” The reading is shown by a fine blackened steel indicator needle which is overlaid by a brass set needle attached to a knurled knob rove through the glass crystal. The set needle indicates the last reading and hence the weather trend. This is all housed in a very high quality solid bronze case in a lustrous high polish. The top of the case has a pivoting brass suspension loop for hanging. The back of the case also has a small aperture by which to adjust the barometer reading. 5 ¼ inches in diameter, 6 inches high inclusive of the hanging ring and 2 3/8ths inches deep. Virtually perfect original condition in all respects. The movement is very lively and highly accurate. A better barometer of this vintage and type is not to be found! 449

22.07  BAROGRAPH.  Late 19th century English barograph of finest quality made by one of England’s most respected instrument makers of the period, “J. HICKS, LONDON” as inscribed on the maker’s plaque affixed to the front of the case.  This beautifully-made weather instrument employs 7 evacuated metal bellows connected to a complex linkage system attached to a stylus with an inking pen.  The linkage is all brass with steel pivots, mounted to a heavy solid brass bedplate.  The pen records a trace on the revolving drum.  A lever protruding through the front of the case allows the pen to be lifted from the drum when not in use.  The brass drum is motivated by a jeweled clockwork mechanism which runs for 8 days on a single wind, making a revolution once a week.  To these ends there is a Fast/Slow adjustment feature under the removable brass cover and a built-in winding key.  The paper graph encompassing the drum is marked from 29 to 31 inches of barometric pressure in 1/10th inch increments on the y axis and is marked Monday through Sunday in 2 hour increments on the x axis.  The glazed wooden case is made of rich mahogany with all brass fittings.  The original glass is old and wavy.   The instrument measures 11 ¾ inches long by 6 inches wide and 7 inches high.  Complete with the original ink vile with ground glass stopper and contents!  The entire presentation is in outstanding original condition, fully functional (the clock keeps good time) and is complete with several original old recording charts in pristine condition. Was 1295   NOW! 495  

James Joseph Hicks worked as an optical, mathematical and philosophical instrument maker from 1861 into the very early 1900’s.  He began work at 8 Hatton Garden, London.  As his business grew his premises expanded to 8, 9, 10 Hatton Garden from 1885 onward.  Born in Ross Carbery, County Cork, Ireland, he apprenticed to the famous barometer maker, L. P. Casella in London.  Hicks made and sold all types of barometers, becoming one of the most prolific makers in England.  He was a staunch Catholic, presenting meteorological instruments to the Vatican, and was made a Knight Commander of St. Gregory.  (Edwin Banfield, “Barometer Makers And Retailers 1660 – 1900.”  1991, Baros Books, Trowbridge, Wiltshire.)

22.30  VERY EARLY ANEROID BAROMETER.   Important English barometer made shortly after the time of its invention.  This rare, surviving example has a silvered brass dial with unusually fine markings showing atmospheric pressure calibrated in inches of mercury form 27.7 to 31.3.  Subdivisions are in 2/100 increments marked in 10ths.   The semi circular scale is augmented by the weather indications “STORMY, Much Rain, Rain, CHANGE, Fair Set Fair, and VERY DRY.”  The readout is indicated by the delicate blued steel needle.  The center of the dial is marked “ANEROID BAROMETER.”  Below the center is the curved mercury thermometer identified as “FAHRENHEIT’S THERMOMETER.”  The degree scale ranges from 6 to 140 degrees calibrated in 2 degree increments marked by 20’s.  A gilt reflector ring encompasses the dial, set in an elaborately-tooled brass bezel over the glass.  The solid brass case is a thing of beauty, retaining its bright brass finish.  The back is marked with a logo of an anchor flanked by the initials “DC.”  A small aperture is on the right for setting and calibrating the instrument.  For hanging it is equipped with a pivoting brass loop at the top.  Excellent condition throughout with expected very minor flaws.  The  dial is original and untouched.  Both the barometer and thermometer functions are lively and accurate – amazing considering this barometer is approximately 160 years old!  Museum quality.  595

In Edwin Banfield’s reference book, “Barometers Aneroid and Barographs,” 1985 Baros Books, Wilshire, England, the author depicts a barometer on page 15 with the caption, “Fig. 9 Early aneroid barometer by E. J. Dent, Paris, c. 1848,  (Science Museum, London).”  The dial with it small, plain calibrations  is seen to have a curved mercury thermometer reading “FAHRENHEIT’S THERMOMETER.”  In addition, it has an unusual stippled brass bezel ring encircling the dial which is identical to the example offered here.   Of added note, it does not have the typical set needle seen in a majority of later barometers.

The mercury-in-glass thermometer was invented by physicist Daniel Fahrenheit in Amsterdam in 1714.  By 1724 Fahrenheit had developed a temperature scale using ammonium chloride and ice to set a “0” point, and ice forming on still water as “32.”  A third point of calibration was “96,” the temperature of human blood.  Further refinement of the scale eventually determined the latter to be “98.6.”

Soon after the invention by Fahrenheit, a Swedish scientist, Anders Celsius, devised the Celsius scale in 1742.  It used 2 points of calibration, “0” for freezing water and “100” for boiling water.  Although Celsius gained quick acceptance in most countries, England continued to use Fahrenheit until the 1960’s, and it is still used in the U.S. today. 

It is a testament to the very early origins of this barometer that the maker saw fit to “personalize” the thermometer by referring to it as “Fahrenheit’s,” thus differentiating it from the more recent Celsius. Scale of the time.

22.24  “MOUNTAIN” BAROMETER.  Quite scarce early 1900’s American “Mountain Barometer” with the unique feature of being adjustable for altitude (elevation).  This precision instrument was made by the Tycos Company of Rochester, N.Y. as signed on the bottom of the white enameled dial.  The dial is calibrated for atmospheric pressure  in inches of mercury spanning the wide range from 25 to 31 inches in 2/100th increments marked by 10’s.  It bears the standard weather indications “@STORMY @ RAIN, CHANGE * FAIR @ VERY DRY @” with the added notations “LOW & HIGH.”  At the top it is marked “PAT. AUG.-18-1914.”  The reading is indicated by a fine blued steel needle overlaid by a brass “set needle” with knurled brass knob rove through the beveled glass cover.  The body of this instrument is solid bronze in its original flawless golden lacquer finish.   The back of this instrument bears the rare patented feature which allows it to be adjustable.  It consists of  a knurled disc calibrated in feet of elevation from 0 to 3,500.  The engraved instructions read, “FOR A SEA LEVEL READING ROTATE THIS PLATE UNTIL THE ARROW ON THE CASE POINTS TO THE ALTITUDE OF YOUR LOCALITY.”  The back also has an aperture for a set screw to further adjust the movement.  The top is equipped with a pivoting brass loop for hanging.  5 ¼ inches in diameter and 6 inches high overall.  Absolutely perfect condition is all respects.  The precise mechanism is lively and accurate.  The best!  349

22.27  FRENCH BROMETER with THERMOMETER.   Finest quality late 19th century aneroid barometer made by the highly respected Parisian barometer making firm of Paul Naudet as indicated on the small “PNHB” logo at the top of the dial.  This handsome example has a silvered open face which frames the complex movement within.  The dial indicates atmospheric pressure in inches of mercury calibrated from 27.8 to 31.2 in 2/100th increments marked by 10ths.   It shows the standard weather indications of “STORMY, RAIN, CHANGE, FAIR and VERY DRY.”  At the top of the aperture it is marked “Made In France” and “HOLOSTERIC BAROMETER” (without liquid).   Of much added value and desirability is the fact it is fitted with a large curved mercury tube marked “FAHRENHEIT THERMOMETER” registering an exceptionally broad range of -18 to 148 degrees in 2 degree increments. The barometric read-out is made by the very precise blued steel indicator needle, overridden by the brass set needle attached to a knurled knob.  The knob runs through the beveled glass crystal with its old wavy glass.  The solid rose bronze case is of traditional form with a pivoting suspension loop at the top for hanging, but also fitted with a stout brass hanger for hard mounting to the ship’s bulkhead top and bottom.  This lovely antique barometer has just been professionally serviced and both functions are guaranteed to be lively and accurate. 5 ¼  inches in diameter,  2  1/8 inches deep and 6 1/8 inches high overall.  In our 35 years handling antique barometers, there are no finer examples than those marked PNHB.  For an accurate, functional instrument which is very decorative and has value as an antique, this is it!  The best.  595

22.21  CARVED SHIP's BAROMETER. Very handsome mid-1800s Captain’s cabin  barometer undoubtedly from a sailing ship.  This lovely example combines form and function in a  shipboard instrument which has a hard-fired white porcelain dial calibrated in inches of atmospheric pressure from 27.7 to 31.3.  It also has more unusual weather notations reading:  GALES, STORMY WET CHANGEABLE, FINE, CALM, and SET FAIR at the top and -.FALLS.-MORE WIND FROM S.WLY., S.E., S.W. ARM, WET (then the trident) and, -.RISE.- N.ELY, N.W.N.E OR LESS WIND. COLD DRY.   Key words are highlighted in RED.  Of added appeal, and certainly increasing its value as a real ships barometer, is the fact that an old fashioned anchor is depicted at the center of the dial and Neptune's trident is shown at the bottom.  While unsigned, it is our opinion that this barometer was made by Martin of Swansea, a noted English ships' barometer maker circa 1860.  It has a brass bezel with thick beveled glass through which the brass set needle overlies the black indicator needle.  The body of the barometer is carved in the traditional ropework manner out of rich dark oak.  The original heavy brass hanging bracket is countersunk on the reverse.  The entire instrument measures 9 ½ inches in diameter and 3 1/4 inches thick, while the dial itself is 6 1/4 inches across. Outstanding, pristine original condition throughout!  Fully functional and accurate.  Truly a fantastic example.  579

According to Edwin Banfield in Barometer Makers And Retailers 1660-1900, 1991, Baros Books, Wiltshire, England, Felix Martin was a watch and clock maker in Swansea from 1850-1870.  We had and sold a nearly identical barometer with a plain, but signed dial by this maker.

22.26   ANTIQUE FRENCH BAROMETER.  Finest quality late 19th century aneroid barometer made by the highly respected Paris barometer making firm of Paul Naudet as indicated on the small “PNHB” logo at the bottom of the dial and again on the back of the brass case.  This handsome example has a silvered open face dial which showcases the complex movement within.  The dial is marked with the very broad atmospheric pressure range in inches of mercury from 25 to 32 in 2/100th increments marked by 10ths.  The dial shows the standard weather indications of “STORMY, RAIN, CHANGE, FAIR and VERY DRY.”  At the top of the aperture it is marked “Made In France” and at the bottom “HOLOSTERIC BAROMETER” (without liquid).  The barometric read-out is made by the very delicate blued steel indicator needle, overridden by the brass set needle attached to a knurled knob.  The knob runs through the beveled glass crystal with its old wavy glass.  The solid brass case of traditional form is in its original lacquered  finish.  There is a pivoting suspension loop at the top for hanging.  This lovely antique barometer has just been professionally serviced and is guaranteed to be lively and accurate. 5 ½ inches in diameter and 2 inches deep.  In our 35 years experience with barometers, none finer were produced than those marked PNHB.  For an accurate, functional instrument which is very decorative and has antiquity value, this is the way to go!   Priced to sell.  389

The first practical aneroid ("without liquid") barometer is generally attributed to Parisian, Lucien Vidie in 1843, who was awarded an English patent for his device in 1844.  Vidie's patent rights expired in 1859, allowing other makers to produce instruments.  The most successful makers in France were Naudet, Hulot & Cie, who reportedly made 20,000 instruments between 1861 and 1866.  (1)

Another reference to the firm was made by Middleton who states, "...there were several makers soon after the patent expired in 1859, the most successful being Naudet, Hulot, & Cie.  According to Le Roux they made 20,000 aneroid barometers between 1861 and 1866.  They called them baromètres holostériques...  references occur in the continental literature to Naudet barometers and to holosteric barometers for the rest of the nineteenth century.  They acquired a great reputation and were widely imitated." (2)  Middleton goes on to state,  "For many purposes aneroids continued to be made - and are indeed still made - of a form very like that arrived at by Naudet, Hulot & Cie about 1860." (3)   In the Appendix is an entry for a barometer held in the collection of the Smithsonian Institution, Washington, D.C.  It reads, "230,002  A "Holosteric  Barometer- Compensated, "made by Naudet & Co. Marked on the back of the case, U.S. Signal Service" (4) indicating manufacture around the time of the First World War.

Surprisingly, little is written about the innovative and prolific Paris aneroid barometer maker, Pierre (alternatively "Paul”) Naudet, although it is known that his firm was begun in 1861 and continued producing aneroid barometers into the 1930's. 

The dating and meaning of the markings HBPN (alternatively PNHB) are less clear.  An entry for a barometer sold on eBay indicates the markings refer to "Hulot, Pertius & Naudet, Paris, barometer makers in the 1930's.  However Andy Demeter, writing about the history of the Chelsea Clock Company notes, "With the possible exception of recording barometers, Chelsea did not assemble holosteric or aneroid movements for their barometers preferring to purchase them from the legendary French maker, Pierre (alternatively Paul) Naudet.  His firm's trademark is typically found in a circle on these early barometer dials with the letters "HBPN" as an abbreviation for "Holosteric Barometer, Pierre Naudet." (5)  On page 220 a barometer dial is pictured with the caption, "1909 Pierre Naudet barometer."

22.25   IDENTIFIED U.S. MARITIME COMMISSION BAROMETER.  High quality World War II vintage merchant ship’s barometer made for the U.S. Maritime Commission by the famous American scientific instrument making firm of “Taylor Instrument Companies, Rochester, N.Y., U.S.A.” as marked on the pristine white dial.  This pilot house barometer is marked “PRESSURE Inches of Mercury Compensated” from 27.7 to 31 .3 in 2/100th increments marked by 10ths swept by a blackened steel indicator needle.  The dial is protected by its glass crystal housed in the original black Bakelite ship’s bulkhead-mounted case measuring 6 ½ inches in diameter on the flange.  This sealed unit has a pivoting brass cover on the back which protects the aperture provided for adjusting the reading.  It is the first such feature of this quality we have yet encountered in a barometer.  Attached to the barometer is an old work tag stamped “MACK BRUNTON BRYAN” then penned in old ink, “Merchant + Miners Trans. Co.”  This barometer is in excellent working and cosmetic condition in all respects.  Its indication of the barometric pressure is lively and accurate.  349

22.01  U.S. MARITIME COMMISSION BAROMETER.  Highest quality marine aneroid barometer made by the Friez Company of Baltimore, Maryland for the United States Maritime Commission during the early days of World War II (1943), as engraved on the silvered brass dial.  This all brass instrument with beveled crystal features a dial marked in an unusually broad range of barometric pressure from 25 to 32 inches in 2/100ths increments marked by 10ths.  The reading is indicated by an ornate blackened steel hand overlaid by a brass set needle attached to a knurled knob running through the clear beveled cover.  Internally it has a temperature compensated dual bellows system with a very precise rack and pinion linkage, seen only in the finest quality U.S. Weather Bureau instruments of the era.   The solid brass case is of traditional maritime form with a flanged bulkhead mounting plate 6 inches in diameter.  The dial itself measures 4 5/8 inches diameter set within the original reflector ring.  Outstanding original condition in all respects.  This barometer is very sensitive and extremely accurate.  A wonderful example of superlative American ingenuity during the most adverse  times.  295

22.02   EARLY WALL BAROMETER.   Elegant furniture-grade English wall barometer with the silvered brass dial signed “Lione Somalvico & Co., 125 HOLBN HILL LONDON” in beautifully hand-engraved script.  In a rare departure from typical instruments of the period, the dial is also engraved with images of a squirrel and an owl perched on a branch.  Also known as a “banjo barometer,” this type of domestic barometer was popular from the late 1600’s into the 19th century, reaching the zenith of demand at about the time this example was produced.  As such, competition amongst manufacturers was fierce and each strived to outdo the other.  This is a wonderful result of that competition.  The circular 8 inch dial is hand-engraved with a scale indicating atmospheric pressure in inches of mercury from 28 to 31, calibrated by 5/100th  increments.  Of added charm and appeal are images of the bird and squirrel adjacent to the center arbor.  The barometric reading is indicated by its fancy, delicately pierced blued steel needle.   It is overlaid by an equally ornate brass set needle which is rove through the glass to a knurled knob.  The glass is contained in its heavy brass bezel measuring 9 ¼ inches in diameter.  Above the dial is the very large mercury Fahrenheit thermometer calibrated in 2 degree increments from -10 to 120 marked by 10’s.  It also bears the traditional temperature indications:  “Freezing, Temperate, Sumr Heat and Blood Heat.”  At its heart this barometer has a glass “J tube” mercury column with glass weights and brass pulley system -- totally functional and accurate.  The beautifully-veneered mahogany case has exquisite marquetry inlays of varietal woods in the form of floral rosettes and sea shells.  Also there is very fine string inlay of holly wood along the entire perimeter of the body.   At the top is the “broken arch” pediment and brass urn finial in excellent condition.  It measures 40 ¼ inches tall by 10 inches wide.  There are a couple of very minor chips in the edge of the case near the top of the thermometer.  These are insignificant and are mentioned here only in the interest of full condition disclosure.  The fact is, this handsome barometer is surely one of the best we have had the pleasure to offer in our 35+ years.  A working, completely original barometer of the highest order,  over 185 years old!  Was 2995  NOW! 1995

From the estate of a prominent civil engineer and collector of high end barometers in Southern California.

Edwin Banfield, “Barometer Makers And Retailers 1660-1900,” 1991, Baros Books, Wiltshire, England lists “Lione Somalvico & Co. as having worked at 125 Holborn Hill, London from 1810-1830.  (p. 202)

Due to its containing mercury, this item requires special shipping.  It is not transportable via regular commercial carrier.

22.04 U.S MARITIME COMMISSION BAROMETER.  Authentic World War II era ship’s aneroid barometer made for the “United States Maritime Commission” by the wartime manufacturing firm of “Fee And Stemwedel, Inc. Chicago” as marked at the bottom.  This highest quality weather instrument features a pearl white dial indicating “PRESSURE Inches of mercury Compensated” calibrated in 5/100ths increments and marked in tenths from 27.7 to 31.3 inches.  The reading is shown by a very fine blued steel indicator needle overlaid by a brass set needle attached to a knurled knob.  The instrument is housed in its classic wartime Bakelite case with mounting flange measuring 6 ½ inches in diameter and is 3 inches deep.  The dial, with silvered reflector ring, measures 4 ½ inches across.  A small aperture on the back is marked “Regulator” for adjusting the reading.  Outstanding original condition in all respects and extremely accurate.  The quality of this instrument is superb, necessitated by the rigors for which it was intended.  189

22.06  ANTIQUE BAROGRAPH.  Extraordinary, scientific grade turn-of-the-last-century weather instrument made by the well known English makers “Short & Mason, London.”  This lovely, fully functional instrument embodies the long-standing British penchant for form and function.  As such, the precision mechanism with gilded brass works and hardwood housing is a thing of beauty.  It employs 12 evacuated silvered bellows connected with a complex linkage system to a stylus holding an inking pen.  The linkage is all brass with steel pivots as mounted to the gilded brass bedplate.  It is decoratively-engraved with its makers, “Short & Mason London.”  The quill-type pen records a trace on the revolving drum.  A lever mounted on the front of the bedplate allows the pen to be lifted from the drum when not in use.  The brass drum is turned by a jeweled clockwork mechanism which runs for 8 days on a single wind, making one revolution per week.  To these ends there is a Fast/Slow adjustment feature under the removable brass cover and a separate winding key.  The interchangeable chart paper graph encompassing the drum is marked from 28 to 31 inches of barometric pressure in 1/10th increments on the “y” axis and is marked Monday through Sunday in 2 hour increments on the “x” axis.  The glazed wooden case is made of rich mahogany with all brass fittings and is supported on 4 wooden feet.  The sturdy scalloped base is complete with pull-out drawer containing 2 compartments.  The forward compartment is filled with original, unused gummed graph charts.  In addition there is an original pamphlet reading “S and M STORMGRAPH RECORDING BAROMETER, Directions For Use.”  The second compartment is for storing recorded charts.  The upper removable case contains its original old glass on all 5 sides.   This instrument measures 14 3/8 inches long by 8 ½ inches wide and 8 1/2 inches high.  Complete with the original ink vile with ground glass stopper and contents!  The entire presentation is in an outstanding state of original preservation, fully functional (the clock keeps good time) and is complete with at least 20 spare recording charts in pristine original condition.  Price Request 

22.08  ANEROID BAROMETER.  Large, late 19th century aneroid barometer made for the English speaking market.  This especially handsome barometer has an all brass case with a colorful open face porcelain dial.  It is beautifully marked with an impressive range spanning 21.5 to 31.5 inches of mercury, designated in tenths and calibrated to 2/100th increments.   It is marked “Aneroid Barometer” at the bottom and bears the standard weather indications “Stormy, RAIN, Change, FAIR and Very Dry.”  A fine blued steel needle indicates the current reading overlaid by the brass set needle which records the reading as operated by the knurled knob in the center of the beveled glass.  The complex high quality movement with brass backing is visible within the open dial.  This precision weather instrument measures 6 ¾ inches in diameter and is 2 ¼ inches thick.  A pivoting brass suspension loop is equipped at the top for hanging.  A small aperture on the back of the case is provided for accurately adjusting the reading.  Excellent original condition with a nice statuary bronze age patina to the brass.  569

22.09  WEATHER GLASS.   Authentic hand-blown glass weather instrument known as a weather glass, storm glass or thunder glass, as found in the homes of sea captains from the 17th through the19th centuries.  This exacting copy consists of a one piece glass vial with a hanging eye at the top, a curved swan’s neck spout, and terminates in a bulbous glass bottom.   It is complete with a hand-wrought hanging bracket of copper and brass.  In use the glass is partially filled with water so that the level can be seen within the spout.  Weather changes accompanied by varying atmospheric pressure are evident in the rise and fall of the water level in the spout.  The hanging bracket measures 12 inches tall overall and the glass is 9 inches tall and 3 ½ inches wide.  Perfect condition.  49

Bert Bolle in “Barometers,” 1982, Argus Books, Watford, Herts, England discusses the Thunder glass or “donderglas” stating, “The title of “weather glass” is more apt than “barometer” in the context of the instrument shown.  A barometer is a measuring instrument, as such, has a scale; a thunder glass does not have a scale.  Therefore the term “weather glass” is more suitable for this, nonetheless, decorative antique."

"In the illustration, one can see that the glass is hung from a small hole at the top and is filled with liquid.  This can be water with a dye if desired.  The instrument, about 10 inches high, functions on the principle that variation in air pressure will cause fluctuation in the water level in the spout.  Without a doubt, this instrument is only partly reliable as it is greatly influenced by variations in ambient temperature.  However, if the thunder glass is hung in a place where variations in temperature are minimized, it is an excellent indicator of variations in air pressure."

"Thunder glasses were characteristically Dutch and production got under way sometime in the early 17th century."
This example comes complete with the original instructions printed when we commissioned an old-school glass blower to make a few of these instruments in 1983.  Since then they have been in storage for more than 30 years!

22.11  IMPORTANT ENGLISH  BAROMETER.   Truly fit for a king (or at least a prince married to a queen!), exceptional mercury wheel barometer from the 2nd quarter of the 19th century.  This precision weather instrument, also known as a “banjo barometer," has a large hand- engraved silvered brass dial signed, “CHADBURN Optician To  H.R.H.  The Prince Consort. 71 Lord St. Liverpool, No. 539. PATENT.”  It is calibrated in inches of mercury from 28 to 31 in 2/100th increments with the standard weather indications, “Stormy, MUCH RAIN, Rain, Change, Fair, SET FAIR and Very Dry.”  The dial is protected by a thick beveled glass crystal set in a solid brass bezel ring measuring 9 inches in diameter.  The barometer pressure reading is indicated by a large, very fine, blued steel needle overlaying a second brass “set needle”  which indicates the previous reading.  The set needle is operated by an ivory knob just below the dial.   Above the dial is mounted a very large mercury thermometer with a silvered brass scale calibrated in degrees Fahrenheit from 9 to 114 in single degrees, and engraved with the archaic notations, “Freezing, Temperate, Sumr Heat and Blood Heat.”  This impressive furniture grade piece is made of sculpted rosewood with elegantly carved scroll accents.  But what really sets this barometer apart from most of its genre is it incredibly fine mechanism.  It utilizes the standard “J tube” mercury column with indicator needle actuated by a float connected to rack and pinion linkage for a super accurate reading!  The movement is accessed by a long hinged wooden door on the back and the top is equipped with a brass mounting bracket for hanging.  This finest quality barometer measures 37 inches tall overall and 10 ¾ inches wide.  The dial itself is 8 inches in diameter.  Outstanding cosmetic and fully functional condition.  Price Request 

Because this item contains mercury, special handling in transport is required.

Charles Henry Chadburn was a Mathematical Instrument Maker, Optician and Philosophical Instrument Maker at 70 Lord Street, Liverpool from 1845 to 1861.  He won the favored patronage of His Royal Highness Price Albert and a prize medal at the Great London Exhibition of 1851.  Later he joined his brothers John and William to establish the highly respected firm of Chadburn Brothers which operated well into the 20th century as nautical instrument makers and chandlers in Sheffield and Liverpool.  This barometer represents a very early example of Chadburn’s most exquisite output.  Prince Albert died in 1851, and obviously this barometer predates his death.

22.12  WHEEL BAROMETER.  Very impressive mid-19th century English wheel-type wall barometer also known as a “banjo barometer.”  This large, instrument-grade piece of furniture is fashioned from exquisitely-carved hardwood providing a most appealing presentation for the barometer and thermometer functions.  The red alcohol thermometer registers on an engraved silvered brass scale reading from 20 to 120 degrees Fahrenheit marked in single degrees with the classic notations, “FREEZING, TEMPERATE, SUMr HEAT and BLOOD HEAT.”  This amazing thermometer has a HUGE bulb!  The barometer function is beautifully portrayed by the hard fired porcelain dial calibrated in hundredths of inches marked in 10’s from 28 to 31 inches of mercury.  The precise reading is shown by the fine, pierced blued steel indicator needle.  The secondary brass set needle, of equal quality, is actuated by an ivory knob just above the dial.  The center of the dial is decorated with an elaborate starburst design of floral motifs.  The barometer indications are further embellished by the classic notations “STORMY, MUCH RAIN, RAIN, CHANGE, FAIR SET FAIR and VERY DRY.”   The internal mechanism of this barometer is the standard “J tube” with glass weights and pulley system connected to the indicator needle.   It is fully functional and properly calibrated.  The body of this Victorian masterpiece is beautifully carved on its top, bottom and sides, with flourishing floral motifs and scrolls.  The dial is protected by a heavy beveled glass crystal set into a solid brass bezel.  This statuesque furniture piece measures 42 ¾ inches tall overall by 12 ½ inches wide at the widest.  Totally functional and accurate, in remarkable original cosmetic condition.  Because it is of the mercury type, it does require special handling in transport.  Accordingly we have cut our $3900 price in half, making it a literal steal!  Please compare equivalent offerings elsewhere.  1995 

22.13  BAROMETER / ALTIMETER.  Large, extra nice late 19th century English gentleman’s traveling barometer with the dual function of being an altimeter. This unusually large portable instrument is in the form of a pocket watch with bow and retains its bright brass finish.  The silvered brass dial is hand-engraved.  It is calibrated from 25.5 to 31 inches of barometric pressure, divided down to 2/100ths of an inch.  It is marked “Compensated” and “Made in England”   The outer rim of the dial is marked in “FEET” from 0 to 5,000 divided down to amazing 20 foot increments!  To set and record a reading the rim revolves.  This is provided with pinpoint accuracy by the extremely fine steel indicator needle which is little more than a hair’s width in diameter!  This instrument is complete within its silk and satin-lined, hinged wooden case with Moroccan leather cover.  A small spring-loaded lever with brass button latch secures the case when closed.  3 ¼ inches in diameter and 1 ¼  inches thick.  The dial itself measures 2 ½  inches across.  Fully functional and accurate.  595

22.14  POCKET COMPENDIUM.   Rare, most impressive late 19th century gentleman’s travelling companion which provides the quadruple indications of barometric pressure, altitude, compass course and temperature!  This compact, highly precise scientific instrument is a mere 2 inches in diameter on it solid brass, gilt-washed body with two sides.  The barometric side features a silvered brass dial calibrated in inches of mercury from 18 to 31 in 5/100ths increments.  The movement is marked “Compensated” (for temperature) and is signed “Henry Kahn & Co.. SAN FRANCISCO.”  The knurled, rotating outer rim constitutes the altimeter function which reads from 0 to 15,000 feet, calibrated in 50 foot increments.  On the reverse are the compass and temperature functions. The high quality classic compass card is “Singer’s Patent” type on mother-of-pearl, with agate pivot and innovative black and white card for easier night viewing,  The card is divided into the single points of the compass with the cardinal and intercardinal points identified and North designated by a harp and star.  The circular mercury Fahrenheit thermometer is a thing of beauty, registering in 2 degree increments from 8 to 150 degrees marked in 10’s.  At the top of the instrument is a pivoting suspension loop for hanging or attachment to a watch fob.  The entire presentation is 2 ¾ inches high inclusive of the loop and one inch thick.  Outstanding original condition in all respects noting that the gilded surface has worn with normal use.  Totally functional and accurate.  A real delight. 795 

Samuel Barry Singer was a master mariner from Southampton, England.  His simple, but effective design was a unique half black, half white dry card dial which was much easier to see in low light.  The northern half was blackened while south half of the dial remained naturally bright with its mother-of-pearl surface and minimal markings.  The star and lyre symbols had metaphorical meanings.  They represent the constellation Vega known as the “Harp Star,” one of the brightest in the Northern hemisphere.  Singer was granted his patent in July 1861.   (Kornelia Takacs, “Compass Chronicles,” 2010, Schiffer Publishing Ltd., Atglen, PA.)

22.16   STICK BAROMETER.  Genuine, second half 19th century ship’s gimbaled mercury stick barometer.  This early barometer is most certainly of English manufacture, and is what is known as the “trap door” type, owing to the hinged door covering which protects the registers and thermometer.   The silvered brass register scales are calibrated in tenths of inches from 27 to 31 on the right and bear the engraved weather notations “STORMY, MCUH RAIN, RAIN, CHANGE, FAIR, SET FAIR and VERY DRY” on the left.  The red alcohol thermometer mounted in the door is calibrated in degrees Fahrenheit from -2 to 120 in two degree increments on its silvered brass scale, with the traditional notations “Freezing, Temperate, Sumr Heat and Blood Heat.”  The hinged door secures on the right with a hook and eye closure.  This long barometer has a body of rich mahogany with brass furniture.  There is a blank brass maker’s plate above the registers and the top is fitted with a pivoted bras ring for hanging.  The bottom contains the very heavy brass cistern cover containing the boxwood cistern within.  The cistern is equipped with a thumb screw for making this barometer portable.  This marine barometer is equipped with its original gimbal and mounting bracket.  The solid cast brass bracket is hinged so that when not in use the barometer can be folded up against the ship’s bulkhead for safe keeping, suspended by the loop at the top.  38 inches tall overall inclusive of the suspension ring.  The register is just under 2 inches wide.  The gimbal bracket is 4 ½ inches wide at the pivots and extends 8 ½ inches from the bulkhead.  All functions of this barometer work perfectly.  The barometer and thermometer are accurate and the barometer gimbals with a smooth tight action.  Excellent original condition throughout exhibiting age but respectful care in use.  Bargain priced.  1695

Because it contains mercury, this barometer may require special preparation and handling in shipment.

22.17   ANEROID  SHIP’s BAROMETER/THERMOMETER.   Superb, early 1900’s ship’s mounted barometer.  Certainly one of the finest of its kind to be found, this extra high grade barometer was made by the legendary French firm of Paul Naudet for the equally famous American nautical instrument makers and chandlers, “T. S. & J.D. Negus Navigation Warehouse 140 Water Street, New York,” as engraved on the pristine silvered brass dial.   This aneroid barometer is also marked “HOLOSTERIC (meaning “solid, without liquid”) BAROMETER” and “Made In France” at the top of the dial.  It is calibrated in inches of mercury from 27.8 to 31.2 in 2/100th increments and is boldly marked with the standard weather indications “STORMY, RAIN, CHANGE, FAIR and VERY DRY.”  Adding to its functionality and desirability the lower half of the dial is equipped with a curved mercury thermometer reading “FAHRENHEIT THERMOMETER” calibrated in 2 degree increments from 6 to 136 degrees.  A fine blued steel needle indicates the barometric pressure while a brass set needle attached to a knurled knob shows changes.  The set needle is rove through the beveled glass crystal, held in place by the brass bezel.  The barometer case is all brass with three  brass mounting lugs screwed and soldered to the back for very secure mounting to the ship’s bulkhead.  In addition to an adjusting screw, the back of the case is also marked with the familiar Naudet logo of “PNHB” (Paul Naudet Holosteric Barometer) in a circle.  The dial measures 5 inches across while the entire instrument is 5 ½ inches wide and 2 inches thick.  Magnificent original condition with a nice old age patina.  Fully functional and accurate.  They don’t come any nicer!  549

22.19  MOUNTAIN BAROMETER.   Scarce early 1900’s American-made aneroid barometer for use at altitude.   This lovely precision weather instrument has a white enameled brass dial protected by a glass face.  The bottom of the dial is signed “Taylor Rochester, N.Y. U.S.A. / Toronto, Canada.”  At the top it is marked “PAT. AUG. 18-1914.”  The dial is calibrated in inches of mercury reading from 26 to 31 in tenths of inches, divided by 2/100ths.  It is also marked with the standard weather indications “~STORMY – RAIN –CHANGE * FAIR – VERY DRY~.”  A blackened steel indicator needle points to the precise reading, overlaid by a brass set needle connected to a knurled brass knob through the glass.  The barometer is contained within its lovely solid bronze case with pivoting suspension loop at the top.  The unique feature of this barometer is on the back.  Rotating the knurled brass plate moves the entire  movement within, thus setting the reading for a given altitude.   The rim of the plate is calibrated in “FEET” of altitude from “3500 to 7000” in 100 foot increments.  Instructions read “ROTATE THIS PLATE UNTIL ARROW ON CASE POINTS TO THE ALTITUDE OF YOUR LOCALITY.  PATENTED AUGUST 18-1914.”  5 ¼ inches in diameter and 2 ½ inches deep.  6 ¼ inches tall overall including the suspension loop.  This fine instrument is fully functional and in a virtually pristine state of original preservation.  395
