The shutter-spring is from an earlier Zorki-2C/C and changed. Also the back was changed with a screwed plate. And there is an other shoe.

Some kind of the same can be found on fotoua (Zorki-2 type-3) only with it seems to be an earlier Zorki-2C with a long self-timer same like on a real Zorki-2.
And here is the catch. Zorkis of course have an arrow for the frame-counter. This arrow is missing on this #57089422 and missing on the fotoua type-3 because they had their arrow on the original top-plate which was longer and under the frame-counter.
