Hi Jan,
I have been experimenting with this self-timer mechanism and attempted to follow your instructions. I have cocked the shutter and set speed to 1 sec. Then I have tried to wind the key but it appears to already be wound or it doesn't advance more. The dial seems stuck on 10, and it will not move to reset to V. I am thinking the mechanism maybe be jammed and is stuck. Any thoughts on this as I do not want to force. When shutter is tripped, the 1 sec works but no self-timer?
Regards,
