This is an amazing piece of engineering. A working roll film camera with a minimum of moving parts and all stamped out of sheet metal. The single lens is visible on the top of the film holder (right view). This thing is very reminiscent of a tea tin! It was made by The J.E. Mergott Co. of Newark, New Jersey. The "stereo" lenses for the view finder are as good as the main lens. The photographer looks down onto a ground glass screen to view the scene. One shutter speed or time exposure are the only options. 4-3/4 x 4-1/4 x 2-3/4 inches.
