Description

ANTIQUE VINTAGE SPENCER AMERICAN OPTICAL MODEL GK DELINEASCOPE PROJECTOR W CASE. Shipped with USPS Priority Mail.
I picked this up at an estate sale and really don’t know much about it. It looks to be in good condition but I haven’t tested anything. Also looks like it came out of San Mateo Junior college. The strap on the case is broken, but all else looks to be in good condition.
I found this on the internet:
American Optical was established in 1833 as a small spectacle manufacturing concern in Southbridge, MA. The company grew rapidly, gradually acquiring additional facilities for manufacturing a range of optical products. In 1935 this expansion lead to its purchasing the Spencer Lens Company of Buffalo, New York. For several years after the acquisition the Spencer Lens Company continued operation under its own name before becoming known as the Instrument Division of American Optical Company in 1945.
