Hi folks,

can anyone help me?

The notch should hit the spring when the shutter is in its unwound position. In fact this is the shutter brake for the first curtain.

Thanks a lot Valkir, in fact I didn't know what was his function!

It's dual purpose - latch when fully wound and brake at the end of the shutter travel. Earlier Zorki 4s don't have the latch function and it's just a brake.

I think mine has only one function, because there's just one spring.

If you can find a later one or a 4K as a donor, you can fit the later latch/catch to it. Gives improved accuracy on some slower speeds, especially 1/15th. I have an older Zorki 4 that I did this with. All depends if you can find a "scrapper" for the parts.
