Princelle shows a Fed B of 1938 with a lens like that - on page 98 of the second edition. The same page has a warning about counterfeiters.

Not sure on this one, it looks like the Russian pre-war F2, which are not Zeiss design.
They are copied to increase value of the pre-war FED. Quite how they fake them is a mystery, as the F2 Zeiss glass would not appear to fit the older collapsable mounting.
They are strictly for display anyway, as most surviving older Russian lens were not good lenses, not bad design, but poorly made.
The Academy in Moscow knew well advanced optics, but the Kremlin only authorised scientific uses for most advanced designs. It only changed after the seizure of Zeiss, and the German staff taken to the USSR.

I've always understood that that pre-1950s FED lenses needed to be shimmed individually to a given body, which rather defeats the idea of changing lenses, and the matching only lasts as long as the shims are in place.

It was the body that was shimmed under the mount to match the lens, which was taken as "correct". They used cigarette paper or foil. This meant that if the lens was all right, then the bodies could be swapped around, but inconsistances in the lenses meant the bodies varied a bit, but nothing too serious. Leica shimmed their bodies in exactly the same way, but used special standard lenses and gauges.
After the war Zeiss staff taught the Russians to use master lenses to set the bodies, but the Russians changed to die cast shutter crates and bodies, which were accurate enough to overcome any problems.
As usual with Soviet cameras it all depended on whether the work was done correctly.
Early lenses were also a different pitch L39 thread, possibly in case Leica sued over patents, although Russia usually disregarded all patents.

First, Hi Geoff and welcome to the forum. Read through the old topics and drag them up. I find it very interesting when new members do that.
It would appear original. Thanks. I was thinking the FED logo looked modern, I didn't realise it was in use before the war. The seemingly high gloss on the lens barrel looked too new and shiny for something over 70 years old.
I have a little interest in Russian cameras, but not a passion like others on this site and as a result I haven't been to every web page not have I read Princelles.
Thank you all for your information and Geoffox23 specially.

The prewar FED f2 lens was uncoated and didn't produce very good images--very prone to flare, too. All the pre-war FEDs (and a few manufactured right after the war) had a different thread pitch that the later lenses and won't fit the later bodies. The lens in question appears to be legit but is of primary interest to a dedicated FSU camera collector (I'm not that dedicated).
