The 1890’s Keystone device was used to test eyes with an instrument and has an illuminated milk glass opening where different transparent overlays were clipped on. Consists of an aluminum base that tilts a clip board with a milk glass opening. Behind the board is a mounted light source that can be turned on in the back (was rewired by someone recently black cord).

I thought this would make a cool side light and you can clip transparencies, film strips , or just photos.
