Description
This is a compound monocular with coarse and fine focus, triple nosepiece, square stage, inclination joint, sub-stage diaphragm, sub-stage mirror, horseshoe base, and wooden case. An inscription on the tube reads “BAUSCH & LOMB OPTICAL CO. / ROCHESTER, N.Y. U.S.A.” Another reads “Pat. Jan. 5, 1915.” The 111688 serial number indicates a date of 1916. This belonged to Herbert E. Ives (1882-1953), an American scientist and engineer who, like his father, Frederick Eugene Ives, specialized in optics and photography.
