Non-folding packfilm camera, named Big Swinger, made of a rigid plastic body. It has a meniscus lens (single element, plastic), a single speed mechanical shutter, a built-in flashgun for AG-1 bulbs (missing here), a fixed focus and a plastic wrist strap. The exposure setting is assisted via a built-in photometer, similar to the one found on the model 20 Swinger. Only 3000 ASA (B&W) film can be used in this camera.
It is essentially a Swinger except for the film size. This was the first of the rigid plastic packfilm cameras produced. Original retail price: $24.95. This example here comes in its original packaging, with an instruction manual.
