Canon IIb Shutter Speed Dial (Pin Placement)

[Fixcinater]

Canon IIb, has a couple issues that seem to be related. There seems to be no damage from what I can tell, but I've not been able to find an exploded view or even photos with the top plate off to verify.

1. Winding on is possible, but the curtains only move fully across the frame if the shutter speed is set to 1/1000. Any slower speed allows proportionately less distance to be wound. At the lowest setting, the curtains barely move across at all.
   
2. The shutter still cocks and will fire at any setting. Very little to zero space between the curtains no matter the speed selected.
   
3. Slow speeds haven't been touched and won't be until I get the fast speeds working right.

Anyone have a photo of the shutter selector on an early Barnack Canon they could provide?

Follow up after doing some more disassembly: the release lever for the slow speeds was on the wrong side of it's retaining post hence getting caught in the shutter speed selector dial as it was rotating around and stopping it's progress.

Flipped it to the outside of the retaining post and it winds on correctly at all speeds.

Slow speed actuating rod was out of place as well, so those work now too. Now to see about patching the pinholes in the curtains (or maybe replacing them).



Overall, not as bad as I thought. Taking the body off the shutter crate isn't so horrible.
