21.20  LARGE HAND-HELD TLESCOPE.  19th century mariners’ telescope consisting of a main tube and 4 separate extending brass “draws.”   Possibly English in origin, it is more likely of French manufacture with its textured leather covering over the brass body.  This high quality optical instrument has a large achromatic (doublet) objective lens and a 4 element erecting system which produce a highly magnified upright image of extreme clarity.  All of the lenses are perfect with no chips or flaws.  This handsome telescope measures exactly 36 inches in length when fully extended and 10 1/8 inches when closed.  It is 2 ¼ inches in diameter.  It is complete with its ocular eye piece with a built-in pivoting dust cover.  The draws of this telescope slide in and out properly and there are NO dents.  The brass surfaces retain their original age patina and the leather covering is virtually perfect.  Overall a very, very fine example of this type of long glass approximately 125 years old at a super bargain price.  WAS 895 NOW!  379

5.45/21.19   WORLD WAR  II  U.S. NAVY PERISCOPE.  A truly amazing find!  This is a World War II vintage turret gunsight telescopic periscope from a capital battleship of the era!  The telescope body is steel with brass components.   Its state-of-the-art optics produce a highly magnified upright image crucial to the big ship’s mission.  The ocular is a typical cylindrical eyepiece with rotating focus.  The original fitted rubber eye cup is still present and quite flexible.  The internal optics also produce both a reticle for tracking the target and a built-in degree scale.  The optics work just as a submarine periscope providing a horizontal image in-line with the target over a vertical distance of more than 3 feet.  The maker’s inscription on the side of the main body reads:

“U.S. NAVY BUR. OF ORD.
PERISCOPE MK 23
INSP’R  B.B.A. No. 26
U.S. NAVAL GUN FACTORY
WASHINGTON D.C.  1942”

 This periscope measures 42 inches tall overall and 10 inches in diameter at the widest.   What is especially nice is the periscope is contained in its original dovetailed oak carrying box (crate) measuring 4 feet long and 13/2 inches wide.   The entire assembly weighs 192 pounds.  There are substantial fold-down handles for carrying on each end.  What a rare and unusual offering!  949 

We have seen a similar telescope mounted through the roof of a Cape Cod home allowing the owners to take in the surrounding scenery from the comfort and privacy of their living room!

21.15 IMPORTANT AMERICAN KALEIDOSCOPE. A very rare original example of the proud inventions coming out of the fledgling American industrial giant in the second half of the 1800’s. It is a Bush kaleidoscope, widely recognized as the best of its kind ever made. This patented “deluxe model” features Bush’s standard cardboard main body covered in faux black shark skin. The non-magnifying eyepiece has a glass lens. The “working end” of this kaleidoscope is one of Bush’s rare output featuring a rotating cardboard barrel with turned ebony spokes rather than his more common brass examples. The cylinder contains an array of ingenious liquid-filled glass vials and other intricate glass objects enclosed in glass. These unique items were a source of yet another Bush patent. On the top, the barrel isl labeled with the Bush trademark in gold, “C.G. BUSH & CO. PROVIDENCE R.I.” having an outline of his kaleidoscope, then “PATENTS REISSUED NOVEMBER 111873.” What makes this model “deluxe” is his patented quadrapedal walnut stand with legs which can be removed for transport. One of the legs is impressed “C.G. BUSH PAT.” Even in these days of computer graphics and neon, it is hard to believe what amazingly colorful and geometrically perfect imagery Bush was able to capture in his pre-electricity device, actually tilted downward to be illuminated by simple candlelight. Seeing is believing. Modern day video games don’t even compare. Nothing short of incredible! 13 inches high overall and 10 ½ inches long. The base footprint is 6 ¾ inches square. Amazing original condition, producing equally amazing images guaranteed to wow and delight! 1695

Charles Bush (Busch) was born in Prussia in 1825. In 1847 he immigrated to Plymouth, Massachusetts and took up the rope-making trade of his father. Quite unexpectedly, his ongoing examination of rope fibers under a microscope ultimately lead to an interest in kaleidoscopes. Around 1870, while living in Providence, Rhode Island he developed and began manufacturing a high quality kaleidoscope with the help of his wife. His output was deemed “extraordinary” and his kaleidoscopes quickly found world-wide demand. Bush was granted several American patents in 1873 and 1874. One was for “new and useful objects for the object box.” Another was for his four-legged stand which could be disassembled for transport. That patent was dated Nov 17, 1874. By 1875 Bush was credited with having made 5,000 such instruments before he and his wife moved to Claremont, New Hampshire. Unfortunately, fewer than 1,000 of his original output are known to have survived today. As such the demand for authentic examples is very keen. Auction sales of these scarce instruments show prices of $1,500 and up, depending on condition, especially for the rare deluxe models.

21.06  TELESCOPE TRIPOD.  Genuine early 19th century table tripod for a premium quality library telescope of the period.  This authentic, heavy solid brass tripod is of English origin with lovely Queen Anne cabriolet tripod legs which support a gradually tapered strut.   This strut supports the telescope mount at the top.  The mount is fully articulated with train and elevation functions which are smooth and tight with no play – as required of such a quality instrument.   24 ½ inches long overall.  19 inches tall as configured.  The footprint is 14 ¼ inches on the three legs.   Weight 8 pounds.   Outstanding original condition in a high polished brass finish with preservation coating.  Guaranteed to be over 100 years old.   695

A telescope adapted to this tripod, will easily double in value.

21.04  ANTIQUE TELESCOPE.  Very scarce octagonal barrel captain’s spyglass dating from the early 18th century.  It is a genuine relic from the early days of sail made in England which features a long 8-side barrel carved from a single piece of rich mahogany.  This old sea veteran has several distinctive features which reveal its great age.  It has the early form reverse taper characteristic of telescopes manufactured from the 1680's.  The objective end with traditional brass collar has a sliding lens cover housing its single piece objective lens measuring only 7/8ths inches in diameter!  The draw tube contains only three (not the usual 4) erecting lenses.  These single element lenses are held in by threaded retainers, not rolled in as with later 18th and 19th century telescopes.  The ocular consists of a later knurled brass eye cup with built-in pivoting dust cover.  Another early aspect is the fact that the draw tube slides in and out of the barrel freely with no stop.  In combination the all original lens system provides a magnified image with the telltale “chromatic fringe” characteristic of the earliest telescopes.  Cosmetically it is in outstanding original condition with no dents cracks or other flaws – just great old age.  25 inches long closed and 30 ½ inches long extended.  A beautiful example approximately 300 years old. Certainly a museum piece!  Price Request

The technology of lens making and the grinding of optical glass was in its infancy at the time this telescope was made.  Glass, without occlusions was hard to make.  Accordingly, lens makers reverted to small, thin glass lenses which could be enhanced by increasing their focal lenth.  The result was the charateristic long telesope barrel with very small objective lens.  But Peter Dolland's patent of the achromatic lens in 1758 changed telescope manufacturing for the ages.

21.03   U.S. NAVY TRIPOD TELESCOPE.   Absolutely the ultimate in U.S. Naval optics, this is a pre-World War II vintage flag bridge telescope.  A precious few such telescopes were also configured for exploratory landing party use and were mounted to their rarely found U.S. Navy terrestrial tripods..  Because of the stresses and abuse that such arduous use inflicted, few survived.  Represented here is a very scarce original example in virtually perfect condition in all respects!  Made of heavy solid brass this telescope has the finest state-of-the-art optics of its time produced by the highly respected Bausch & Lomb Optical Co. as marked on the silver maker’s plaque on top of the barrel:  “SHIP’s TELESCOPE Mk I MOD.  BU. SHIP’S U.S. NAVY (N) 255, 1940  B & L OPT CO.”  The barrel has two sighting pins mounted on top and a built-in sun shade protecting the 3 inch objective lens.   A large handle is attached to the left side for conveniently training and elevating.  A set of internal rotating filters are provided for maximum clarity in sunlit, hazy or low light conditions.   They are selected by means of a knurled brass knob just below the eyepiece.  The ocular provides a 28X image of exceptional clarity and brightness.  Of immense added value and versatility, there are an additional 4 interchangeable eyepieces of 12, 14, 22 and 32 powers! Focusing is accomplished by turning the knurled adjustment ring with a range of -4 to +2 diopters in ¼ increments.  The telescope body is supported by its extremely heavy thick bronze collar with trunnions suspended in the equally heavy solid bronze yoke.  Removal of the telescope when not in use is made by loosening the hinged trunnion caps with knurled locking lugs.  The yoke has a stout bronze support spindle which fits snugly into the tripod “spider,” complete with bearing and even a zerk grease fitting!  The end of the spindle is finished off with an extra large brass cap nut.  The yoke bears a silver maker’s tag reading, “MOUNT For SHIP’s TELESCOPE Mk I Mod.  BU. SHIP’S 1940 B & L OPT. CO.”  the spider is also solid bronze and is marked in high relief “U.S. NAVY Tripod model 660 U.S. Metal Products Co., New York.”  A brass collar fits over the spindle allowing the height of eye to be raised or lowered by 5 inches.  The high quality tripod legs, made of finest hardwood maple have all brass fittings and are tipped with bronze “feet.”   A central brass chain allows for splaying the legs to different widths.  This feature allows for further height adjustment and stability.  The legs are detachable from the spider by means of large brass butterfly wing nuts.  The barrel of the telescope measures 28 ½ inches long as pictured with protective screw-on ocular cover.  The barrel is 4 ¾ inches in diameter.  The entire assembly stands 64 ½ inches tall as shown.  This measurement is with the 5 inch height adjusting collar inserted.   The footprint of the tripod as shown is 29 inches between each leg.  The condition, both cosmetically and functionally of the entire unit is nothing short of spectacular -- particularly in light of the fact it is over 75 years old! At the time of its manufacture, this unit cost the Government more than the price of a car. SOLD

21.79 EXTRA FANCY VICTORIAN ERA STEREO VIEWER AND MAGNIFIER.  This beautiful, high quality optical instrument is as decorative as it is functional.  It consists of three-tiers of ebonized hardwood profusely engraved with floral decorations embellish in gold.  On the top front is a large monocular lens for viewing photographs in detail.  Below it a pair of oculars are for viewing stereo cards.   A height-adjustable pierced wooden support mounted on two brass rods is provided for holding a card or photo.  It is also adjustable for depth, sliding back and forward in grooves on each side.  The front of this viewer is hinged with a brass “stay” on the right to lock it in the upright viewing position.  When not in use it folds closed on a friction latch.  The bottom tier is equipped with a wooden track and folding arm which allows the viewer to be inclined to one of three preset angles.  The front bears the oval brass maker’s plaque reading “76  .UNIS . FRANCE  3   STEREOSCOPES -  PARIS”  10 ½  inches long by 6 ¾ inches wide and 3 inches thick when closed, elevating to a working height of 16 ¾ inches.  Superb original condition. 1395

This offering comes complete with several stereo viewing cards with extremely interesting subject matter.

21.86  EARLY TELESCOPE by IMPORTANT MAKER.  Especially rare, 10-sided, reverse tapered spyglass made by the famous London optician and nautical instrument maker George Adams.  This wonderful surviving example of a decahedral telescope is signed on the single draw in elegant cursive script “Adams, London.”   Evidencing its early origins this spyglass has an unusual 5 element erecting system in the single draw vs. the usual 4.  The lenses are held in by threaded retainers instead of being “rolled in,” as exemplified in later telescopes.  Together with the singlet, non-achromatic objective lens 1 1/8 inches in diameter, the system provides a sharp, highly magnified image with the typical peripheral chromatic aberration characteristic of pre-1750 telescopes.  The barrel is constructed of one solid piece of mahogany, hollowed out in the traditional decahedral form.  The draw, with early-form “nipple” has no stop, meaning it will pull free from the main barrel.  Again this is a characteristic indicative of only the earliest hand held telescopes.  Both of the spring-loaded objective and ocular dust slides are in place and operate properly.  The overall condition of this telescope can only be described as nothing short of amazing original condition in consideration of its seaborne life spanning more than 260 years!  The barrel is in its original finish with expected minor scuffs and mars from actual use.  All of the brass components have acquired a rich, deep age patina.  All 6 of the original glass lenses are in perfect condition.  31 inches long overall.  The main barrel measures 24 ½ inches long and is 1 ¾ inches thick at the widest.  Another of our truly museum quality offerings representing a real prize for the finest collection.   2600

George Adams (the first) was without question a premiere English maker of his time.  Born in 1698, he was apprenticed to James Parker in 1724 and began his own business at Shoe Lane, London in 1733.  In 1750 he received a patent for his telescope and was awarded the honor of appointment as maker to the Prince of Wales, George III, in 1760.  (Gloria Clifton, “Directory of British Scientific Instrument Makers 1440-1851,” 1995, The National Maritime Museum.)

Peter Dollond (1731-1821,) son of inventor John Dollond, was widely credited with producing an effective achromatic lens, for which he was granted a Royal patent in 1758.  Up to that time limitations in glass making and lens grinding had made it necessary to manufacture small, thin lenses with long focal lengths in order to obtain maximum magnification.   Accordingly, early high-powered refracting telescopes such as this example, required unusually long barrels in relationship to the diameter of their objective lens.

21.4  BINOCULAR MICROSCOPE.   High grade 19th C. English microscope made for the American market, signed and serial numbered on the base "R. & J. Beck, London 7072." and further engraved on the main tube "J W QUEEN & Co. Agents, Philadelphia & New York."  This finely crafted all brass compound microscope features adjustable Wenham-style binocular body tubes mounted on a sturdy base and stands 14 inches tall as shown. It is complete with a total of 4 objectives and 4 ocular lenses.  It is housed in a lovely African mahogany box with brass furniture measuring 16 inches long.  The lower till houses numerous glass slides while the upper section holds the additional optics, with 11 slots being empty including a separate slot for a light magnifier which is also missing.  Of course the beauty of the innovation embodied in this microscope was the fact that the researcher could view a particular object with both eyes providing a clearer stereoscopic subject.  This rare instrument is in excellent, untouched original condition with most of its original lacquered surfaces.  It is functional and all adjustments operate smoothly and properly.  A most handsome presentation! 2195

The body tubes of this microscope were designed by W. H. Wenham in 1861, and are adjustable by means of a knurled knob that controls a rack and pinion gear set.  A triangular base supports the limb, which has an adjustable inclination angle through a series of holes in the limb that fit a tabbed hinge plate.  Coarse focus is achieved through a set of knobs that move the inner pillar tube up and down through a rack gear set.  The top of the pillar contains a fine focus knob.  A circular stage contains a central aperture and has a slide carrier to assist in translating specimens during viewing.  According to Turner, this form of the microscope stand was designed specifically to accommodate the Wenham binocular tube and was called "The Popular Microscope".

Richard and Joseph Beck joined in a partnership as opticians at 31 Cornhill, London from 1867-1894.  They were noted for their fine quality microscopes, and were admitted to the Microscopial Society of London.  

James W. Queen & Co. were in business as opticians at 48 Chestnut Street, Philadelphia from 1860-1893.
