I've had this camera on display. Never tried to use it. I doubt the bellows are light tight but they could easily be "painted" internally on the corners if you wanted to use it. The only thing I really see wrong with it is the brass badge on the bottom of the case that identifies the model is missing. The lens is in good shape but the shutter is gummed up.
