Manual focus 4.5 x 10.7 cm format stereo camera released by Rietzschel in 1914. The lens board can be slid sideways to allow for panoramic photography instead of stereo. The lens' front elements can also be removed to increase the focal length of the lens. There's an infinity focus mark on the focus scale to accommodate this. Various lens options were available.
