Indeed one characteristic for classifying early FEDs was "focusing tab at 11 o'clock", 9 o'clock etc

Sorry guys for digging out this. I have the same issue with my Fed-1 and its Industar-10 lens. I had taken it off to clean the lens and lubricate it. I felt it a bit loose, not firmly attached, while trying to take it of (the lens) and I had realized that the screw next to the focusing tab was jamming in the holes over the screws of the mount on the camera body. I removed completely that screw to take the lens off.
After cleaning it up, putting the lens back to the body, after screwing the lens all the way inwards, the focusing tab had parked just in front of the viewfinder!
I had searched quite a bit, and in a forum in Russian I was told that the mount on the body has a mark engraved on it at 9 o'clock. I have to tighten the screw next to the focusing tab as much so that the lens get screwed on the body with that screw as close to that mark on the mount as possible.
Is that correct?
I wish I could take off the back of it to verify correct focus.

Nikos72,
I'm a bit confused by your description of the problem. Do you have a photo showing your situation?
From what I can gather, it sounds like one of the lens mount screws is a tad proud and catching the lens as it is fully mounted/seated. If so, the offending screw is where the focus should be (no pun intended). The countersink might have some gunk in it that prevents the mounting screw to fully seat into it, causing the head to protrude slightly above the mounting ring plane (flange).
Or, your problem is something completely different.

rfaspen,
My problem is, or should I say was, that the focusing tab before the lens removal and cleanup was parked at 9 o'clock. After cleanup, while screwing it in all the way the tab was parked at 1 o'clock obstructing the composition viewfinder of my Fed.
After looking into it, I have been advised to adjust the screw that lies a bit further away from the focusing tab so that the lens when screwed in, the tab is parked again at 9 o'clock.
I will add tomorrow a couple of photos explaining this.

Did you remove the lens mount ring / flange from the body? If so, that would be the most likely reason for the problem. The lens mount may have been reinstalled with a different orientation. Easy enough to do because the 4 screw holes around the mount are equidistant and you can remount the ring in any rotated position.
But, there is a relieved area on the underside of the mount ring that goes to the top (allowance for the rangefinder arm) that would make it somewhat obvious if the ring were repositioned CW or CCW. The little black line on the side of the mount flange ring should be at 9 o clock when you are viewing the camera from the front.
If the lens mount wasn't removed and reinstalled, you're implying that the disassembly of the lens has caused the new park position. I'd need to see/read more description of this problem. I have an I-10 and Fed 1 (and others) here to check.
Have you tried mounting any other lenses on this body? Any non-FSU lenses?
