Hi -- I'm new here and glad to be a member. I just received a Mamiya 6 V folder from Japan. I had been looking for a while for one, and finally found one with a decent, non-hazed lens. Now that I have it, I looked at some on-line loading videos, and I have an issue that I'm hoping someone here may be able to solve. My camera seems to have the 6x4.5 mask. However, I received it with the mask attached to the metal rollers, but the rollers are unattached from the inside of the camera. I'm assuming this means the camera arrived broken in that respect, is that correct? Also, when I load the camera and try to wind on to the first frame, I thought this model automatically stopped at counter #1, without needing to use the red window for the first frame. When I tried to do this, of course I wound the entire roll onto the take-up spool and wasted the roll. I tried re-rolling the backing paper to practice, but the same thing happened. Any suggestions? Many thanks in advance.
