21.54 FRENCH OPERA GLASSES. Lovely pair of 19th century opera glasses by the noted makers “Lavista, Paris” as delicately engraved on each of the eyepieces. This high-quality optical device features twin tubes providing depth-of-field viewing superior to a telescope. They are totally encrusted in luminescent mother-of-pearl with gilded brass connectors. Even the draw tubes are adorned with tight sections of M.O.P! These provide a unique “deep” quality on their surfaces. The twin glasses focus with a smooth tight action activated by a knurled M.O.P. wheel at the center. This offering is complete in its black leather carrying case with purple satin lining. It is in remarkable, virtually pristine condition. The glasses themselves are in equally fine condition belying their century plus old origins. The glasses are 4 inches wide in sum, with each objective lens measuring 1 ¼ inches in diameter. Fully extended the set measures 3 1/8 inches long. The leather case is 4 ½ inches wide by 3 inches high and 2 inches thick. Amazingly the case still retains its original sturdy strap handle and original button snap closure. These are features rarely found in such outstanding condition! This set would make a treasured gift to a special loved one… at that, for a very reasonable price. 189

21.53 VERY EARLY TELESCOPE. Remarkable late 17th or very early 18th century telescope by the noted Italian inventor and optician “LEONARDO SEMITECOLO” as printed on the base of the main tube. This hand-held mariner’s telescope is constructed entirely of heavy vellum with turned horn fittings. The main barrel is beautifully embellished with floral and geometric designs. It expands with 3 draws to a focusing point of infinity marked on each of the draw tubes. The collars holding the tubes are turned bovine horn in near perfect condition. But even more remarkable, both the ocular and objective lenses still retain their original screw-on horn dust covers! The fact that these separate items are still together after more than 300 years is miraculous! The optics are entirely original and provide a magnified upright image. This telescope was manufactured long before Peter Dollond’s introduction of the achromatic lens in 1750, so the telltale “chromatic fringe” on the periphery of the image is present. This is a good indicator of age. What is most important is the state of preservation. Made after Galileo’s model, using delicate materials, this optical instrument is in amazing condition. 12 ½ inches closed extending to 34 ½ inches extended at infinity. Without a doubt museum quality of the first order. Price Request

21.51 CAPTAIN's SPYGLASS. Extra nice turn-of-the-last century hand-held telescope by the famous Scottish makers "Dobbie McInnes. Ltd. GLASGOW. SOUTH SHIELEDS. LIVERPOOL & LONDON" as beautifully hand-engraved on the draw. This especially large telescope has a main barrel with a sailor-made sail canvas covering, hand-stitched and finished with handsome Turk's Head knots on each end. This form of Marlinspike seamanship is particularly desired by collectors. The single draw has an early style ocular with sliding dust cover. The objective is protected by a sun shade with sliding dust cover as well. Both slides operate properly. The original 5 element lens system is in perfect condition and provides a bright, highly magnified upright image of extreme clarity. 20 ½ inches long closed and 36 inches long fully extended without the sun shade. Excellent original condition. Approximately 120 years old. 949

The namesake of this nautical instrument company, Alexander Dobbie, established the firm in 1841. In 1881 it changed to Alexander Dobbie & Son. In 1902 the firm was incorporated as it appears here, Dobbie McInnes, Ltd. In 1914 the firm advertised itself as "Manufacturers and patentees of nautical and engineering equipment. In 1921 the name changed to Dobbie McInnes & Clyde, Ltd.

Interestingly, this form of telescope remained unchanged from those made circa 1810 and later.

At the time of its manufacture the magnification or "power" (times X) of early optical systems were not yet calculated. Suffice it to say this state-of-the-art telescope provides an amazingly clear, highly magnified image enhanced multiple times!

21.49 IMPORTANT AMERICAN KALEIDOSCOPE. An original example of the cottage industry ingenuity which propelled America into becoming an industrial giant in the second half of the 1800's. It is a rare 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 features a rotating brass cylinder much like a ship's wheel. The cylinder contains an array of ingenious liquid-filled glass vials, crystals and other intricate objects enclosed in a translucent glass. These unique items were a source of yet another Bush patent. The top of the barrel is stamped with Bush trademark reading, "C.G. BUSH & CO. PROV. R.I." having an outline of his kaleidoscope and then "PATENT REISSUED NOV. 11, 1873." What makes this model "deluxe" is his patented quadrapedal walnut stand which can be disassembled 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. It actually tilts 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 inches long. The base footprint is 6 ¾ inches square. Amazing original condition after150 years, producing equally amazing images guaranteed to wow and delight viewers! 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 taken apart 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 competition 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 such as this.

The renown scientific instrument selling firm "Tesseract" of Hastings-On-Hudson, New York offered a nearly identical kaleidoscope in its catalog 36 (1998) for $1,950 nearly 25 years ago!

21.48 POCKET TELESCOPE. Sweet little gentleman's travelling telescope, also known as an object glass or monocular. This 19th century example has 2 brass draws and a mahogany main barrel. The two glass lenses produce a clear, bright image with enhanced magnification. This high quality instrument measures only 2 ¾ inches closed and 6 ¼ inches fully extended! The draw action is smooth and tight. Perfect overall condition. This is NOT a toy, but a genuine scientific instrument. 149

21.47 SUPERB TRAVELING TELESCOPE. Late 18th or very early 19th century gentleman's pocket compass made by the renown English instrument making firm of "Spencer Browning & Ruft, London" as hand engraved on the first draw. This delightful optical scientific instrument is made of wood and brass with 3 draws. The main barrel is rich mahogany with an achromatic objective lens measuring 1 3/8 inches in diameter. Remarkably this telescope retains its original press-on objective dust cover and its pivoting eyepiece dust cover both still in working condition! 6 ½ inches closed by 13 inches open. The original 4 piece internal lens system combines with the objective to provide a clear, highly magnified upright image free of chromatic distortion. Signed telescopes of this size by important makers are rare. The details of its construction are identical to its larger brothers 5 times bigger! The ultimate miniature for this size and age. 645

The firm of Spencer Browning & Rust appears in the London directories between 1780 and 1784 at 327 High Street, Wapping, London. In 1798 they moved to 66 High Street where they remained for the next 40 years. The production of the partnership was prolific, as it appears they wholesaled their wares to other "makers." The trademark "SBR" can be found stamped on a number of quadrant and octant scales of the period, indicating the instruments were calibrated using Spencer Browning & Rust's dividing engine. (M.V. Brewington, "The Peabody Museum Collection of Navigating Instruments," 1962, Peabody museum, Salem, Massachusetts).
The fact that this telescope is signed "Ruft" with the Olde English version of "s" shown as an "f" indicates its early origins. Inspecting its components, this little telescope was made to the same exacting standards of larger sea captains' telescopes 5 times its size.

21.40 DECORATIVE TELESCOPE by the MASTER. Very rare, particularly nice example of a late 18th century hand-held captain's spyglass by the inventor of the achromatic lens, Peter Dollond, as beautifully hand engraved in script on the first draw "Dollond Day or Night." What is most unusual about this handsome 3 draw telescope is the fact that it is decoratively painted with gilded floral scrolls on a green background on the main barrel. This is most unusual! The telescope has its traditional 4 element lens erecting system, which in combination with Dollond's signature achromatic objective lens, provide a clear, upright, highly magnified image free of color distortion. This telescope measures 35 inches long fully extended and 2 ½ inches in diameter. When closed it collapses to a mere 11 ½ inches. Excellent original condition in all respects. The old style nipple eyepiece retains its original dust slide. The objective cover is away. This is the first such decorated sea going spyglass we have encountered in our 40+ years! 975

Peter Dollond (1731-1821) was the son of John Dollond, a Huguenot silk weaver in Kensington, England. Peter apprenticed to his father in the trade, but his father's amateur interest in optics inspired him so much that in 1850 he opened an optician's shop in London. Two years later his father joined him in the new venture. With his father, and subsequently with his younger brother and nephew, Peter Dollond designed and manufactured a number of innovative optical and scientific instruments. He is credited with inventing the achromatic lens, for which he received a Royal patent in1763.

Dollond telescopes were among the most popular in England and abroad for more than 150 years. Lord Admiral Nelson carried one. Another sailed with Captain Cook to observe the Transit of Venus in 1769. Dollond's more notable customers included composer Leopold Mozart, Frederick the Great and Thomas Jefferson.

After successfully defending a legal challenge of his patent, Dollond's business flourished. His reputation and the fact that his father was a member of the Royal Society, afforded them access to the best raw materials available at the time for their manufacture. This privilege permitted Dollond to maintain an edge in quality over his competitor's optical instruments for many years.

21.39 10-SIDED TELESCOPE. Particularly fine, very rare 10-sided telescope alternatively known as a "decahedral" telescope, from the 18th century. This early telescope, cutting edge for its time, was made by the well known English maker "HAMLIN London" as delicately hand-engraved on the draw tube. Unusual in design, this handsome scope has a large main body carved out of a single piece of solid mahogany tapered and faceted on 10 sides. The classic old fashioned brass objective collar is fitted with a sliding dust cover protecting the large achromatic lens. The ocular end is also of early design with a narrow nipple and sliding dust cover. In evidence of its early manufacture the draw tube pulls out without a stop. Of special note, is the fact that it contains 5 rather than the more common 4 internal lens elements. In consonance, this complex 6 element lens system produces a clear, highly magnified upright image without distortion. A remarkable accomplishment for the late 1700's! The telescope measures 26 inches long closed and 31 inches long extended to infinity. It is 2 ½ inches in diameter on the objective end. The draw itself measures 9 ¾ inches long. Exceptionally well-preserved condition considering an object like this is over 230 years old! Without a doubt museum quality in every sense of the word. 1475

William Hamlin was a respected optician and mathematical instrument maker at 111 Leadenhall Street, London from 1789.

21.32 TRIPOD TELESCOPE by the INVENTOR. Most impressive floor standing tripod telescope by the inventor of the achromatic lens, Peter Dollond, as engraved on the ocular end of the main tube, "DOLLOND * LONDON." This original state-of-the-art optical device of the highest quality dates to the turn of the 19th century (1800). It features a beautiful all brass main tube which boasts a focusing apparatus operated by a large knurled knob on the right hand side of the barrel. The mechanism operates with a smooth, tight action. A ribbed, flared eyepiece is at the terminus of the draw tube. The large objective lens is Dollond's signature "doublet" which provides a clear, highly magnified upright image without color distortion. The telescope is mounted on its heavy solid brass mount which pivots in elevation and rotates a full 360 degrees. It is supported by its 3 magnificent mahogany tripod with brass spreader securing the legs. As configured the telescope measures 55 inches long overall. The main barrel is 43 inches long. The objective lens is 2 5/8 inches in diameter. The height of eye is approximately 65 inches. The footprint of the tripod is 39 inches between the feet. Outstanding original condition in all respects. A spectacular addition to the library or room/balcony with a view! 3289

21.88. LARGE IVORY BINNOCULARS. A really incredible pair of 19th century binoculars with the bodies turned out of solid ivory! This handsome, super high quality optical instrument was obviously designed to be a cut above the usual instruments of its type with leather-covered brass bodies. Most likely of French manufacture this set exhibits the quality and craftsmanship indicative of French opticians in the 1800’s, as exhibited in this particularly difficult medium. The large twin objective lenses measure 2 ½ inches in diameter and are 5 inches wide overall. The gilt brass frames secure the lenses within the solid ivory bodies. Another set of gilt brass frames hold the oculars. Within each is a circular ebony eyepiece. The binoculars focus by turning a ribbed ivory knob in the center, extending from 4 5/8 inches closed to a full 6 1/8 inches. This action is very tight. The all original lenses combine to produce a stereoscope image of great clarity with good magnification and light gathering capability. Remarkably these old binoculars show relatively little cracking expected of such a medium about 150 years old. There is the obvious wear and age patina. The original satin-line leather carrying case is also in remarkable condition, complete with original carrying strap. The case measures 5 ½ by 5 by 3 inches and closes with a brass button latch. 895

This extra large pair is about as rare as it gets. We have never seen a nicer set *anywhere* for sale or on exhibit. Not to mention with the original silk-lined leather case!

21.11 HISTORIC, VERY RARE PRESENTATION TELESCOPE! Without question the most significant presentation item we have offered in our 35+ years, involving the Queen of England and an American President! This classic two-draw mariner’s telescope is all brass with original optics, eyepiece and objective fittings, beautifully-engraved in fancy script on the draw near the eyepiece “Dollond, London, Day or Night” The eyepiece with original dust slide is of the early-form “nipple” type. The perfect 1 ¾ inch achromatic objective lens is protected by a press-fit lens cap with its own sliding dust cover. The body of the telescope is housed in a rich Moroccan leather covering in like new condition. The piece-de-resistance of this offering is the meticulously hand-engraved inscription on the sun shade barrel. It reads:

The inscription is clear, deep and untouched. The surrounding brass has acquired a rich statuary bronze patina that does not appear to have been polished or cleaned since its inception 179 years ago! The telescope itself is in an amazing state of preservation and is fully functional providing a highly magnified upright image of great clarity. The draws pull in and out with a smooth, tight fit. It measures 15 inches closed by 2 ½ inches in diameter and extends to 38 ½ inches long. Without a doubt this exquisite lifesaving relic would find a prominent place in any major American or British Museum. 6295

Even more interesting provenance could be found for this important historical relic by researching the American packet ship RHONE and the British bark BELINDA.

Alexandra Victoria (1819 – 1901) was Queen of the United Kingdom from 1837 until 1901. Her reign of 63+ years was known as the “Victorian Era,” at the peak of the British Empire. It was a period which saw the greatest cultural, political, scientific and industrial changes in world history. Only recently was the duration of Victoria’s reign eclipsed by the current British monarch Queen Elizabeth II.

James Buchanan Jr. (1791 – 1868) was the 15th President of the United States (1857 – 61), serving immediately prior to the American Civil War and the Presidency of Abraham Lincoln. A member of the Democratic Party, he was the 17th United States Secretary of State and served in the United States Senate and United States House of Representatives.

Buchanan was born in Pennsylvania and became a prominent lawyer in the town of Lancaster. He was first elected to the Pennsylvania House of Representatives in 1820 and later won a seat in the United States House of Representatives, aligned with Andrew Jackson's Democratic Party. President Jackson appointed him Minister to Russia. It was during that time he made this presentation on behalf of Queen Victoria. Soon after, Buchanan was elected senator of Pennsylvania. In 1845, he accepted President James K. Polk's appointment as Secretary of State. While in that position, the land mass of the United States grew tremendously with the addition of the Oregon Territory and annexation of the Southwest as a result of the Mexican War. From 1853 to 1856, during the presidency of Franklin Pierce (1853 – 1856) Buchanan served as the United States’ Ambassador to Britain. Buchanan won his party's Presidential nomination in 1856, defeating Pierce and Senator Stephen Douglas at the 1856 Democratic National Convention. He went on to become President, defeating Fremont and Fillmore in the 1856 election. He was succeeded by Abraham Lincoln in 1860.

21.07 17th CENTURY TELESCOPE. Very rare, late 17th or very early 18th century mariner’s telescope in the Galileo style by the Italian master Leonardo Semiticolo as impressed on the ocular end of the main barrel. This 2-draw telescope is made of paper and vellum with turned horn eye pieces, sections and ends. Its clever construction makes for a very lightweight instrument manageable with a single hand. The red orange barrel is decorated with recurring geometric, floral and bead-like designs. The 2 draws are greenish yellow with a mottled surface. Both are marked with concentric rings indicating the position of distention for infinity. The eye piece of turned horn is of the early “nipple” form retaining its original screw-on dust cap. Remarkably, the objective also retains it original dust cover. This is absolutely amazing after more than 300 years! The telescope measures 28 inches long fully extended and compresses to 12 ½ inches closed. The original optics provide a surprisingly clear, highly magnified image with the expected chromatic aberration characteristic of pre-1750 telescopes. Excellent condition in all respects. A true 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 length. The result was the characteristic long telescope barrel with a very small objective lens. But Peter Dollond's patent of the achromatic lens in 1758 changed telescope manufacturing for the ages.

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

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

21.4 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.
