This camera had a few problems before I started to work on it, but I found some more. However, I was able to patch the shutter, clean the outside of the camera and the inside of the lens, and make a substitute part so I could at least shoot a couple of rolls before sending it off for more permanent repairs.

Here is the link to the documentary photos

Nice camera and lens! Indeed quite rare, in the years I've frequented camera shows, I've only seen one.

Hope the slow speed issue is just caused by a misaligned rod and not the slow speed escapement itself.
 
I think the escapement is okay, except for the one second setting (which is very skippy, most likely needs cleaning). When I trip the shutter on 30 or below, it acts like it is at B, but then when I release the button, the speed escapement takes over, and the shutter closes when the time is up.

I think I encountered a film transport problem today. I was at the 22 exposure mark of a 36 shot roll of Ilford FP4 Plus 125, and my finger slipped off the winding lever. However, I was able to trip the shutter, and then continue taking exposures. But as I was winding for the 26th shot, I noticed the rewind knob was not turning. I checked the tension, and it seemed okay. I wound and shot two more times, and still no rewind knob rotation. My biggest fear at that point was that I had ripped the film somehow, because it didn't feel the same. So I started to rewind the film, and it seemed very normal, with tension all the way to the start end of the roll. There was no part of the film left on the spool, and no excessive wear on the spool, or support that I made.

Won't know until I get the film developed what happened, but I am going to do a test with one of my special rolls of film (stuff I find in used cameras, and mark as a test roll, then use it over and over to test the functionality of a camera). I'll load the camera, take the lens off, and mark each frame outline as I run the film through the camera. I should be able to see if there is slippage occuring right away

After running a test roll through the camera, and marking every frame from the front, I noticed that on the B setting, the second curtain would sometimes close when it was supposed to be open. Then the slippage started at around the 28th frame.

I got the second roll of film back from the lab, and there were some nice keepers on it. At least the cleaning job I did on the Canon 50/1.8 LTM seems to be okay.

Here are some examples.

And here is where the film transport messed up.

Film was Ilford FP4 PLUS 125, and I used a Spiratone OR 2 Series VI filter in an Ednalite 617 adapter. Exposure calculation was by Sunny 16.

The YF is now going to be sent to Georgia for a complete overhaul by Mark Hama. I've already gotten the estimate, and although more than I would normally sink into a camera, this one is worth it.
