I agree with justcurious.
The Hensoldt scope has been fitted in Germany, perhaps by Gustav Genschow & Co.
Claw mounts treatment is typical of German trade.
I have seen and sold a lot of BRNO 21/22 and the factory scoped ones usually bear a Zeiss Jena glass on special mounts of the same kind found later on the ZKK rifles.
However a well done German claw mount is a nice addition on such a fine rifle.
