This rare and historical device was invented in the early 1940's by Franz G Back and was patented in the 1950's. The way this device functions is a transformer unit is plugged in the wall and the camera. The camera attaches to this flexible rubber housed hose that goes down the patients throat into the stomach. When the plunger is depressed the body of the camera retracts igniting the arc flash exposing 16 small pinholes taking a picture of the stomach that requires no focusing. The camera is then retracted an screws off the end of the hose. Tiny film that is inside the camera is developed just like regular film and the results are full 360 view of the stomach.

What you will get is the camera with loaded film that is since expired. You can see it by screwing off the end cap as pictured. The camera slides and you can see the pinholes all around the camera. Along with the camera you will get a set of six photos that were developed using this camera and are stamped in the reverse. Very unique and excellent addition to any camera collection or medical museum.
