It was a producer of optical products and machinery particularly in the 1920s. Lens cutters were used to rough cut ophthalmic lenses to shape and size. The lenses were then hand edged with a smooth bevel edge using a rotating polishing wheel. This model of lens cutter was patented in April 1935 although the patent papers were filed in August 1932. The patent is in the name of W A Lockhart assignor to Shuron Optical Company. It is an earlier model of the one at Cat No 1906.
