I recently found a FED passport in a book and it mentions the Industar-10. That's the first link I've seen of the FED and Industar-10. It says:-
Объектив--ФЕД (анастигмат „Индусгар-10“)
с просветленной оптикой No.........…
and even I can translate that as:-
Lens - FED (Industar-10 anastigmat)
with coated optics No........
It's odd that they use the abbreviation "No" as the letter "N" like that doesn't exist in Cyrillic...
FWIW, the passport was for a FED 1 (G), S/No 637 759 and the lens was S/No 048679 and was dated 1955.

PS Has anyone looked at the English repair manual I mentioned above?
