This portable microscope model BPP is a compound monocular with rack-and-pinion, square stage, inclination joint, sub-stage condenser and diaphragm, bar for sub-stage mirror, and collapsible V-shaped base. The mirror and lenses are missing from this example. The inscription reads “BAUSCH & LOMB OPTICAL CO. / Rochester, N.Y. / B L / Z S/ 89205.” Bausch & Lomb boasted that “For physicians, veterinarians, agriculturists and others who desire a microscope for use in the field, there is none superior. The U.S. Government has put it in use after severe competitive trials.”

The “B L Z S” inscription refers to the 1907-1915 association of the Bausch & Lomb Optical Co., the Carl Zeiss Optical Works, and George N. Saegmuller.
