I have a real beater back, there's a crack on the hinge and a crack by the front latch. The hinge holds when it's closed and the latch bit could be epoxied. Or... and this is what I would do, you could stick the film in there and tape the back closed. It's missing the dark slide. Bottom line: 1)It will work 2)It is not pretty 3)Will need a dark slide 4)And glue 15$ shipped in the US.
