Slide Viewers / Film Viewers deals / Photographic Supplies from the Past / 3 Different Viewers

Authentic photo supplies from long ago. Found in a very old photographers studio, 3 slide, or film viewing devices. The green one is from Bausch and Lomb, The grey one is marked "Admiral" and the red one folds and comes from "Ansco". The Ansco viewer works well and folds as it should, nice art deco bakelite style, lenses need cleaned. I'm not sure how to use the green or grey pieces. Price is for all 3 viewers.

The studio operated from the 1920's to the 1960's. I also have 2 photo retouch kits, a darkroom deals light and a group of developing supplies. .
