Cory - works best with a projector w/ 5 bladed shutter... hard to find at the thrift store alas...
Almost totally useless for THIS, I have a couple of Army training film viewers to get rid of. A little screen, with a door to open if you want to project. BUT, the unique part: they have no film gate! The film flows continuously, without jerking, and there is a spinning polyhedronal mirror instead. You can run extremely delicate films, or splice with masking tape! Quality is mediocre, but condition is/was? good.
