Hi...
Do NOT use m39 Leica screwmount and CV lenses on a Fed-2!
It seems that the Ruskies made the "tongue" at the top of the lens
mount of the Body, in such a way so as to support the use of FSU
lenses. Lenses made to the Leica standard, will NOT focus properly.
In any event, good luck.

Some non-soviet LTM lenses
can be used on FED and Zorki. It would be the lenses which have tongue-shaped coupling cams instead of full barrel types which cannot be, and should not be used.
I have used Summitars, Elmar (both 50 and 90), Canon/Serenar 28, 35, and 50mm lenses in many FED and Zorki cameras of various models. I suppose, (not having any CV lenses) that CV lenses with similar coupling cams will mount too. In fact, the 28 I use with my FED and Zorki is a Canon. This lens functions without fail on any FED (except the NKVDs) and Zorki I've put it on, as it would on any Leica or Canon or Epson.
The lenses which I know which should not be used in FED or Zorki are the Summaron 35, Hektor 135, and Canon/Serenar 85, 105, and 135 lenses.
Some FED, particularly the prewar and immediate post war FED-1 and very early FED-2 which would pose problems when used with non-soviet LTM lenses. In fact, many of the later Industar and Jupiter lenses would have fitting problems on these too.
The non-soviet lenses will focus properly if the camera is properly adjusted in terms of working distance and rangefinder calibration for both infinity and near settings. The worst that can be expected in these setups is having the markings of the non-soviet lens stop on either side or even the bottom, instead on top, where it can be read easily.
The Soviet "Leicas" did not come with a tongue- instead they had a slope shaped sensor instead of the roller type found in Leica, Canon, and other Leica type cameras. It is this which makes the use of certain lenses impossible.
