Hello Jacques,
I also don't know when my fake was made and if it is a fake (I believe in that more as it was soviet made by FED). I did not know that the faked lens is so rare, I thought that there were more...
By the way, there is an interesting article by Oscar Fricke, you can find it under
http://fedka.com/Useful_info/Commune_by_Fricke/commune_A.htmThere he writes this (just below the middle of the article):
------------------
While under the administration of the NKVD, the Dzerzhinsky Commune did something which is perhaps unique in the annals of camera history; it copied the Leica in name as well as form. The FED was already a physical copy of the Leica, but some of the cameras were also engraved with the familiar 'Leica' trademark, and some f3·5 lenses were engraved 'Leitz Elmar'. Whatever the motivation, this strange practice persisted over several years, during which an apparently sizeable number of cameras was made. Beyond any shortcomings in workmanship, the give-away features of these cameras was the distinctive FED viewfinder window. The earliest known 'counterfeit Leica' was manufactured in 1936, while the most common year seems to be 1938.
------------------
And there is a picture of a FED that looks like mine, you can see that it has the small depression near the rewind switch lever, the middle front screw is behind the lens mount and it has 3 small screws under the rewind knob, just like mine also has:
