NOT an attempt at high-tech manufacturing for space-age TLRs. The "cameras" here are novelty drinks decanters in my collection.
Not a very good picture, and it doesn't do this curiosity great justice. The Schnapps-O-Flex is a novelty decanter (one of at least two different models I know of) from the late '50s or early 60s. I believe it hailed from Japan - mine has the remnant of a label on the base saying as much.
The flash unit is the stopper, with a cork protruding from its base. Basic, but fun in a rather naff way!
