German or Austrian-made 9x12 stereo plate camera, manufactured in the 1920, possibly made by Camera Industrie Austria. The wooden and cloth covered camera has a Brilliant-type viewfinder in the top. A slotted bar that can be pulled out to one side allows to choose between two apertures. Shutter speeds can be chosen with the pointer (T, B, M). Metal slides allow to expose both halves of the plate simultaneously and thus create a stereo image, or allow to expose one half of the plate only.
