Rupp Sextant

Description
Karl Axel Eriksson, a native of Sweden who became a U.S. citizen around 1910, bought this sextant, secondhand, in England in 1918. He used it for the rest of his life, and believed that it helped him "advance as a sailor."
The sextant has a brass frame. The inscription reads "Michael Rupp & Co. New York" and "English." The silvered scale is graduated every 15 minutes from -5° to +135° and read by vernier with tangent screw and swinging magnifier to single seconds of arc.
Michael Rupp (1818-1899) was born in France, came to the U.S. in 1829, and settled in New York in 1844. By 1855 he was selling chronometers and other nautical instruments.
