Hi, this is my first post although I have read the list from time to time.

I came across an unusual piece today and thought that someone here might be able to identify it for me. I first thought it was a pinhole camera of some sort but now I'm not so sure. As I don't know the posting rules for images I have a linked to some images on photobucket : <http://s188.photobucket.com/albums/z242/PhotoStash07/Cameras/>

The back will accept some kind of film/paper and the lens cap control has "O" and "S" stamped on the body. There are no makers marks that I can see and there is no tripod mounting point either although there was a handle attached at one time.

Has anyone got a clue as to what it is?
