Description
This is a wide field binocular dissecting instrument with very short tubes incorporating Porro prisms, rack-and-pinion focus, triple drum nosepiece, square stage, and wooden box. Bausch & Lomb introduced the basic form in 1925, and various modifications in subsequent years. This example was used at the Rockefeller Institute for Medical Research in New York. The inscription reads “B. & L. O. CO.” The 229585 serial number indicates a date around 1930.
