Microscope

Description
Beck’s Improved National Monocular Microscope is a compound instrument with coarse and fine focus, circular stage, sub-stage bar that holds condenser and mirror and that can swing around the stage, inclination joint, and tri-leg base. This example came from the U.S. Military Academy. The inscription on the base reads “R. & J. BECK / LONDON & PHILADELPHIA.” The serial number 10198 appears on the back of one foot. There is a strong wooden box, and small wooden box holding 3 objectives and 3 eyepieces.
R. & J. Beck began in business, as such, in 1865, and by 1877 had established an American shop under the leadership of W. H. Walmsley.
