I obtained that camera in the very destructed condition. I finisher with the mechanic, repaired the shutter, and at the present am working with the rangefinder.
I partly disassembled the thumbwheel assembly, using the following photos from the net.

However, the I met the problem with the hollow screw, which is able to be seen upon the third photo. The red arrow points at it.
Would anybody be so kind as to inform me, in what direction the hollow screw should be untwisted – clockwise, or in the opposite direction? If somebody already did the same repair, of course.
