21.59 PATENT TELESCOPE. Fine, World War II vintage American telescope made by the prestigious "Bausch & Lomb Optical Co. Rochester, N.Y U.S.A." as impressed on the objective cover and signed on the draw tube. This single draw hand-held telescope has two interesting features.

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 lens. 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 handsome presentation. 1895
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 viewingAccording 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 most 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.
