Help! Tell me what this is:

This take-up "stuff" is for a Contarex, but I don't know how it fits together (it doesn't) and what camera or cameras it fits. I think it's for either a Contarex, Contarex Super SE, or a Contarex N-1.

The pieces don't seem to fit together, though they look like they should.

Any ideas?

When I looked at the pic, before I read the post I thought to myself "Contarex". Fat lot of good that did.
