Description
This example of Leitz’s model IIa is a compound monocular with coarse and fine focus, triple nosepiece, square stage, inclination joint, sub-stage condenser and iris diaphragm, sub-stage mirror, and wooden box. The inscription reads “E. Leitz Wetzlar / No 125871.” The serial number indicates a date around 1909. A brass tag on the box reads “E. Leitz-Wetzlar / NEW. YORK. CHICAGO.” The donor bought this from Dr. Randolph of Upperville, Va., in around 1919, and used it in medical school.
This has a mechanical stage marked “BAUSCH & LOMB OPTICAL CO. / Rochester, N.Y. U.S.A.”
