The Spencer Lens co. was established, as such, in 1893, and introduced its Continental Stand No. 1 in 1896. This was a compound monocular with coarse and fine focus, triple nosepiece, large square stage faced with hard rubber, inclination joint, sub-stage diaphragm, sub-stage mirror, and horseshoe base. The instrument was brass; the base was black. This example is of that sort. The inscription on the tube reads “SPENCER LENS CO. / BUFFALO, N.Y. U.S.A.” The 1225 serial number indicates an early date. The eyepiece is missing.
