Once more, it is very difficult to be affirmative.
This Fed-Zorki is perhaps too much on the Fed side. For me, it's the first time I see a Fed-Zorki with a Fed counter (pins at 15/20 and 0/35), for example. The cover looks correct, as said by Luiz.
Concerning the lens, it is a normal postwar one, usually delivered with the last 1f (coated and new scale). The other lens in the kit is a Fed 2/50mm one. By what we know, the first Fed-Zorki were delivered with re-badged Fed lenses; it's not the case here.
All in all, I rather think of a remount from parts. I have several Fed-Zorkis, including earlier ones. And they all have specific KMZ features concerning the lens, the buttons, the frame counter... For what I know!
You have the taste for risk, Fred!
