Quote: note words as on the post " Bolex - is probably Rolex ".

Bolex is correct.

The Bolex H16 is a 16mm motion picture camera. It is powered by a constant speed, spring-driven motor that is wound via a large winding handle on the side of the camera. It has a variable speed shutter with options for 8, 16, 24, 32 and 64 fps - with the ability to change speeds while the camera is filming.
