Olympus OM Winder 2 with original box and manual!
The Olympus OM Winder 2 is a compact, motorised film-advance accessory designed for vintage Olympus OM system 35mm SLR cameras (such as the OM-1, OM-2, and OM-10). It attaches to the base of the camera, eliminating the need to manually crank the film lever after each shot.
An upgraded version that allows for both single-frame and continuous shooting. It can fire at a speed of up to 2.5 frames per second, making it ideal for tracking moving subjects.
