This is a wide field binocular dissecting instrument with very short tubes with Porro prisms, rack-and-pinion focus, square stage, and wooden box. The inscription on the eyepiece reads “BAUSCH & LOMB OPTICAL CO. / Rochester, N.Y. U.S.A. / 205170.” The triple drum nosepiece is inscribed with the B&L logo and “PAT. 3.1.1927.” The single nosepiece is inscribed “B. & L. O. CO.” The firm introduced the basic form in 1925. The serial number on this example indicates a date of around 1929.
