The Moy has a unique chain drive to a take-up clutch for the winding of the exposed stock in its film box. As far as anyone can tell Moy was the first to incorporate ball bearings in a movie camera. On this Moy one can see a very simple ball bearing incorporated in the shutter drive shaft and there is a hidden ball bearing set under one of the gear clusters. The combination of chain drive, 180 degree shutter and drunken screw movement make Moy cameras very desirable as examples of early
motion picture making.
