FlyingCamera, I do repair motion-picture film cameras. The Bell & Howell Filmo and Eyemo are a class to themselves, you have nitrided steels in them, abrasion resistant. As long as those cameras are oiled, and you can oil them without further ado, you can expose miles of film with one. Other makes cannot be compared to them, a Paillard-Bolex is a mere pile of aluminum before the Filmo, although it has its own refinements.
It is correct that the early Filmo and Eyemo cameras from the twenties run at 8/16 fps only or 16/32. Later models from the early thirties on have the high-speed governor and run 4 through 64 fps. In my eyes the 1931 models are the best, having still the compact three-port turret. When Bell & Howell Co. added the spider turret, magazine, and more stuff the original concept was torpedoed.
If you can’t find anybody who takes your camera for overhaul, I’ll be there. My experience stretches from Paillard-Bolex H, Ciné-Kodak Special, over Pathé WEBO M, Revere 101/103 to the Beaulieu Reflex 16 and others. I can also take care of an ARRIFLEX 16.
