Lenny,
I am not sure it was a self timer on Zorki 1 before
There is the same hole on leather case.
I need to disaemble the camera to see if it is not a later synchro flash plug.
What is interesting is that Aidas said 1B stops at #115000 when 1C starts at same number. This one should be a 1C, but body does not have the decorative rim of 1C and remains as a 1B.....
For Zorki 5, I'll try to give you some news asap.
