The Pathé KOK 28 mm projector
This machine I also bought at an auction. But this model came without an alternator to generate power for the projection lamp.
Since the machine operates lighter without an alternator and flywheel, I use this one to play the films that I own, and to digitize.
It works perfectly, and uses less (arm)power. to show a movie.
I use a 220 / 8 volt transformer for the Illumination lamp.
Also this machine has a metal carrying case, in almost perfect condition.
