What parts are ussually in 35mm motion picture camera?

I read some instructions on how to make a motion picture camera and i would like to try making a 35mm camera since i don't have a 1000 or more dollars to piss away on a camera.

If i'm successful in making this camera and it works. I'll be posting how i did it but one question what kind of parts would i expect to find in a 35mm camera?

I'll make simple verisons of those parts and work from there.

variable-Speed Motor
sprocketted wheels
the shutter
pull-down claw
the gate
registration pins
a viewing system
prism
footage counter
a lens
