IIIF shutter doesn't align

[Yvon]

I did as what the manual described, amazingly I found out that the 40 was actually B and 100 was about 30 degrees distorted from where it was supposed to be. So I have no idea what the B is aligning to.
How can this problem be solved?🙂

The cure is simple- you set it to 40 so that you're sure that the shutter is set to B. Then loosen the set screws which hold the dial in place, and then line up the index marker with B. Tighten screws.

There is a complication though. The IIIf came in about three or four manufacturing variations- how you loosen the screws (and how to access them) on the shutter dial depends on which production variant your IIIf belongs.

lol, i just want to ask, has anyone ever set shutter speed before winding up the film? I had, that was why 40 bacame the B.........this is,fololishness?

I've often done that, intentionally sometimes, with Leica III series cameras. But I've never had the shutter dial shift so that marked values no longer indicate the actual set speeds. It could be that the dial was already going loose when you did that. The extra strain needed to lift and set the dial on an uncocked shutter could have displaced the dial.
