This is the Sekonic Elmatic 8 motion picture camera. It was a couple bucks at a swap meet. The mechanical stuff all seems to run fine, so I've shot a roll of regular 8 mm film on it. It's tricky to get this format developed, (Yale is widely recommended.) so it'll be a little time before I get to see if the ugly beast is actually functional.
Come to think of it, I'm going to need a projector. This could be interesting.
