Very rare French viewer to view stereoscopic images of high quality 35mm film uncut and perforated Jules Richard. Is the camera viewfinder Richard HomeOS, an important precursor to Leica, and the first camera to use film perforated film. The Viewer measures 11 x 6 x 7cm and has a plaque with the words" HomeOS Richard, 10 Rue Halevy, 25 Rue Melingue, Paris" . The viewer is in good condition with no repairs or alterations. Wood is a charming original color and not damaged. Nickel plate is very good, and mechanisms work very well. Two piano-convex lenses that are adjustable from side to side by a lever on the outside, and focused by a rack and pinion system using a knurled knob. Lenses give a good image and not damaged, but there is some dust inside, between the layers. This could be cleaned, but I have not tried to remove it. A jaw mechanism advances the frames operated by a rod extraction, and it works perfectly. Inside, there is a mark of a shield emblazoned with" RF" (Richard Freres?), And a number" 296" Overall, the viewer is in good condition, operating and is original and unrestored. An article very rare and high quality of a historic manufacturer.
