I've come across a swing-back Canon RF camera that I cannot identify (despite owning an L1, P and 7S myself). It seems to be a Canon VT that is missing the trigger wind on the bottom of the camera. I've never seen a pop-up knob film advance on this kind of camera unless it had a trigger base, which this one does not. And note that it has the pop-up rewind knob only seen on the earliest of the swing-back Canon RFs. Peter Dechert makes the point in his book that Canon seemed to occasionally use up parts from previous camera when starting a new camera model, so I suppose it is possible that Canon had some VT parts but no more triggers, so just installed a plain baseplate. I can only think this must be considered a rare variant. Any thoughts from APUG Canon RF experts?
