This is a pretty nifty little projector. The back half holds a bulb. Th the one side a roll of film fits on a spool to pass through the apparatus to a second spool that can be wound. The cord is missing to this interesting piece. It would still be a unique item as a shelf sitter or decorative piece for someone who collects all things photographic.
