A very nice black enamel & lacquered brass microscope by Bausch & Lomb Optical Co., Rochester, N.Y.  It has had very little use and retains all the original lacquer & enamel; measuring 11" high racked down and 15" racked up with rack & pinion focus, fine focus and pull/push to the draw tube. The case contains 4mm and a 16mm nose pieces, both in brass canisters and 5x and 10x eye-pieces. In original mahogany case with handle, lock & key with magnification table to the inside of the door ( no cracks to case ).

With a letter from Bausch & Lomb dated 1970 confirming the year of manufacture as 1908, a photocopy of a B & L catalogue listing microscopes & accessories available, and an interesting notebook handwritten by a previous owner listing ' Optical data, equipment etc and extracts from various specialist authors on the use of the microscope, micro-projecting and microphotography' ( 1938-1945).

A good 3 draw telescope with an objective lens just over 2" across, of brass construction with a leather covered taper barrel, ray shade and eye-piece dust slider. With additional magnification draw tube and leather cover protectors, it measures 10.25" closed and 32.75" fully drawn. The lenses are damage free and give an excellent image when viewing.
