Shows all 27 frames as available. Does not have a film expiration date printed anywhere that I could find but this camera has been kicking around in a drawer for many, many years, so I expect the film is past any expiry date.
Heavy plastic case with rubber seal suggests this could be used underwater but the housing says "waterproof" not "underwater." That may simply mean that the housing can be used past a certain depth. So I won't go scuba diving to 40 feet with it.
