When I saw this tin I recognized the height of a 35 mm film so I talked to myself: "Yes, this might be something", and there it is. Fresh film is loaded on the upper left chamber. It passes through a frame and is collected exposed on the low right chamber. The internal parts are made of hot moulded PVC. The small lever on the external part on the left actuates the shutter. To wind you need to turn a screw on the bottom 2 1/2 cycles. Well, it is a panoramic !
