No sign of damage anywhere on the mirror and the focusing screen is new. The piece is reflective on one side, so it's definitely the mirror. Maybe a remnant of an old repair.

I did check the rotation of the pivot shaft on its own, sorry if that wasn't clear in the previous posts. Regardless, I fixed the problem! There was a piece of broken glass that must have somehow come off the mirror at some point and got lodged under the mechanism that turns the pivot rod...

The toggle action is operating normally. The pivot rod is not rotating far enough in the LOCK position to tilt the baffle below horizontal, which is causing the blockage of the film. I posted a video of the operation here...

This was a good idea, but unfortunately after loosening and retightening it didn't seem to make a difference. I think the issue must be internal. I'm debating on whether I want to go through the hassle of opening it up.

Beau Photo Supplies has someone that they send cameras to. He did some work on this one and CLA'd it, but it was quite expensive.

Thank you! I will check i out.

I think I would rather stick to one lens than waste all that film between frames, but maybe on occasion I could do that. Thanks for responding and the tips!

I think your explanation is likely accurate. I found a parts diagram of the camera (screenshot of relevant page below. unfortunately you have to pay to download or suffer through an ad per page: ) But I'm guessing the spring has failed or the teeth have slipped, and aren't engaging the rod...

I'll try to make another video tomorrow, but I shot a roll before I knew there was a problem and aside from the blocked part of the negative all of the frames were sharp. The lenses appear to be sitting normally.

I can push the baffle down but the pivot rod doesn't move and it springs back up when I take my finger off. And I was unable to move it after taking off the baffle and trying to twist it further. Here is a video of the baffle in motion:

Yes. I can push it to the bottom of the inside of the camera and it springs back to parallel with the bottom when I let go. UPDATE: I removed the baffle from the pivot rod and tried to gently turn the pivot rod past where it stops but couldn't get it to go any further. I suspect that something...

Yes, that's right. Whatever caused the baffle to rotate past 90 degrees from the UNLOCK position to the LOCK position is not working properly (from what I can tell the knob to switch the positions is a 90 degree turn). So the baffle or the springy plate to which it is attached is not getting...

Thanks for responding. Yes, I always retract the bellows before changing lenses and the projection that prevents opening the wire clamp is working as it should. The three screws are in place on the pivot rod. And the movement of the lock/unlock control is the same as you describe it. It seems...

Thanks for the pictures. It appears that when I switch to UNLOCK it looks the same as yours. When it's in LOCK the panel has some spring with the metal part that attaches it to the turning mechanism. I don't understand how it would have turned further to tilt downward in LOCK.

Thanks for the tips. I was switching the lenses throughout this roll before I knew anything was wrong, and every frame has the same blockage. And no matter what order I use the locking and unlocking mechanism, with adjustments to other things in between, I can't get the flap to tilt all the way...
