Bolex SM-8 8mm Film Projector VINTAGE Late Model Sold As-Is for Restoration

We know there is Bolex collector community out there and this later model Bolex SM-8 Super-8 film projector is a good candidate for restoration but needs adjustment and further servicing to bring up to 100%. Vintage sold as-is. We cannot test further because we don't have 8mm film, know nothing about how to adjust, operate or service any further. But here's what we do know and have done:

The back does not have retaining screws
No front cover
No original proprietary cord, but converters are available online that convert to a normal computer-type power cord.

We replaced 3 belts and cleaned up goo from the old ones
Regreased gears, deoxidized controls, cleaned capstan
Treated pinch roller with Rubber Renew which is in good condition
Tested with a homemade AC power cord; motor and spindles turn in both direction, lamp lights on low and sometimes on high, and amp/speaker seem to work
Mechanical counter works
