Locationįrance: Île-de-France, Paris MeasurementsĬlosed: 1 1/2 in x 3 15/16 in x 2 1/4 in 3.81 cm x 10.0076 cm x 5.715 cm At the end of the 19th century, binocular technology finally improved enough to allow viewers to focus both eyes on the same point. Ref: Nicholas Gilman, A Dividend to Labor: A Study of Employers’ Welfare Institutions (Boston and New York, 1899), pp. Baille joined the firm in 1871, and took charge in 1885. 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 carrying case is black leather with a reddish-brown silk lining. The number “61” appears on the central brace as does the Lemaire logo, an image of a bee. The barrels, eyecups and center focusing wheel are covered with mother of pearl. Each eyecup of this small instrument is marked “LEMAIRE FABT * PARIS*.” The objective lenses are 30 mm diameter and the optics are good.
