A PAIR OF BRASS AND MOTHER-OF-PEARL OPERA GLASSES 19th 20th Century, by Lemaire, Paris The bodies encased in faceted mother of pearl, with telescopic mother-of-pearl mounted eye-pieces, the eye-pieces removable, with central focusing wheel, the eye-pieces inscribed LEMAIRE FAB T PARIS, with velvet-lined leather case 2¼ x 3¾ in. Jacques Lemaire began making opera glasses in 1847 and was soon a major manufacturer noted for using mechanization, division of labor and interchangeable parts. The red leather carrying case is probably not original. An image of a bee, the Lemaire logo, appears on the central brace if there was once a number there, it is not now visible. The barrels, eyecups and center focusing wheel are covered with mother of pearl. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.Each eyecup of this small instrument is marked “LEMAIRE FABT * PARIS.” The objective lenses are 30 mm diameter and the optics are good. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. The handle is also covered with inlaid mother of pearl and extends to 10'. The bridge is engraved with a bee and the numbers. The eye pieces say 'LEMAIRE F' followed by some kind of symbol like a small capital T underlined and then 'PARIS'.

This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it. The metal parts of the glasses look like brass and the rest is inlaid mother of pearl.
