Opera Glasses

Each eyecup of this small instrument is marked “LEMAIRE FABT * PARIS .” The objective lenses are 35 mm diameter and the optics are good. The frame is metal. The barrels are covered with black leather. A center wheel adjusts the focus. The words “MADE IN / FRANCE” appear on the central brace, as does the trade mark image of a bee. The number “327412” appears on the eye end brace. The carrying case is black leather with a reddish-brown silk lining.
Jacques Lemaire began making opera glasses in 1847 and was soon a major manufacturer noted for using mechanization, division of labor and interchangeable parts. M.J.B. Baille joined the firm in 1871 and took charge of it in 1885.
