Good wiki reference about the 70 Filmo cameras. All have windup mechanisms unless modified. Some have motor input to drive the mechanism with an external motor. There is a model with a digital resettable footage counter. There is also the HR model with provision for external 400' magazines.
16mm 100' at 24fps is about 3 minutes. The Filmo can easily do 1m on a winding when it is good shape, giving three 1 minute takes. A lot of film work works around this limitation in the pacing of action and scenes.
I have probably 15 of these need to document them.
