SAMOCAFLEX 35 twin-lens reflex camera, made in Japan, equipped with a SEIKOSHA-RAPID lens. - Model Name: SAMOCAFLEX 35 - Country of Manufacture: Made in Japan - Lens: SEIKOSHA-RAPID - Design: Twin-lens reflex camera - Materials: Metal and leather finish - Year of Manufacture: 1955 - Film: 135 film I'm not entirely sure how to use it, but when I advance the film and trigger the shutter using only the winding knob on the side, sometimes the shutter doesn't fire. However, the shutter fires normally when using the winding mechanism under the lens. Is the correct procedure to advance the film using the mechanism under the lens first, and then use the top winding knob to advance the film? - The shutter speed changes, but I think the accuracy is unstable. - The aperture opens and closes according to the aperture value changes. - The lens has little clouding and is in relatively good condition for its age. - The viewfinder is clear and clean. The focus adjustment from the top viewfinder is easy to see and clear, but there is some dust. - The leather covering is peeling off. ※ The camera display stand is not included. ※ No price reduction. Thank you for viewing.
