Cameras do vanish. Especially during a move. I had a pristine Century Graphic with red bellows and 8 backs. Vanished during a move 11 years ago. The only thing I could find was the backs. Then there was the SRT 101b and X-700 that vanished about 5 years ago. And if the missing cameras weren't bad enough, all my Kodachromes of a European trip vanished. We have a cat but he swears he didn't do it.
