HELP! Zorki 4 is only exposing half of each frame!

I have a similar problem with my beloved (my first real camera which I got at the age of 12 in 1991 - the USSR was still existing!) FED-2(e) since it came back from a CLA where it got new shutter curtains:

About 40 % (15 from 38) show this effect, while the others show no problem at all.

Does this only show up when the camera is held vertical? If so it seems that some of the light baffels have come loose. Other problem with FED2 sometimes is that there is some play in the restriction gear, when - after some years of use - its screw has come loose (this of course is an easy fix).

At horizontal orientation 6 out of 24 (25 %), at vertical orientation 8 out of 13 (62 %) are affected.

I just checked the screw, it was still tight.

The effect seem to have disappered or at least I am not able to reproduce it at watching through the shutter while operating it.

Perhaps I have to try a film test...

Is the lens mount fixed well? the 4 screws into the mount are held at the back by two little metal plates, are these still fixed and at their position or have one become loose?
