For sale, a Sankyo XL-420 Supertronic cine camera.  I believe this is Super 8 rather than 8mm but I would advise researching the capabilities of this model in case I'm wrong about that.   The camera is untested and I can't inspect the battery compartment / handle as the unlocking mechanism is jammed (and the coin screw to unlock it is quite worn from what looks like a previous owner's attemps at freeing it.)  Of course the camera can be run from DC power anyway, although this would require an adapter that isn't included.  Finally, part of the rubber eye cup is missing, although I assume this could be easily replaced.
