In my father's estate are a bunch of 8mm films. I have a non-operating
Kodak M77 Instamatic projector.

Has anyone ever taken one of these apart? I need to get to the back where
the drive belt is and I will be darned if I can figure out how to open it.
All I can find on-line is places to spend big $ to buy manuals.

Any help or copies of a manual would be appreciated.

Thanks
