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 Special PackagingBack 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.

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   NOW495  Special Packaging

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.)

22.27  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


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."

22.21  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.

22.25   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

The Merchant and Miners Transportation Company of Baltimore was begun in 1852 to provide passenger and cargo service between Baltimore and Boston. The fledgling steamship line began operations with two wooden hull side wheelers.  In 1859, two iron hull steamers joined the fleet and the port of Providence, Rhode Island was added to their itinerary.  From 1861 through 1864 the company was shut down due to the Civil War.  After a slow return to business as usual the company ordered a new ship in 1869.  By the 1870’s business was again flourishing enabling the company to acquire the Baltimore & Savannah Steamship Company in 1876 to enter the cotton trade between Savannah, Charleston and New York.  The company continued to expand in the 1880’s and added Newport News and Norfolk to its ports of call.  In 1900 a Philadelphia - Savannah service was begun.  In 1907 the Winsor Line of Philadelphia with its fleet of seven steamers was purchased.  A new route between Baltimore and Jacksonville commenced in 1909 and in 1920 a service to Havana, Cuba was briefly operated.   Nassau, Bahamas was added 1939.   As the United States entered into World War II most of the company's floating assets were requisitioned for war duty by the end of 1942.  With the end of hostilities, denied of its ability to generate revenue during the war years, the company’s owners considered it impractical to purchase war weary ships from the Government or to build new ships.  In 1948 the company’s trade ended and it was officially closed in 1952.

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!

22.13  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.)

22.17   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
