[Jay Are]

I bought from a buddy a few. WW2 sniper scopes but I can't find any certain answers as to their authentication so can I get some answers to
1) real WW2 scopes
2)where cAn I find information to read about them?
3)what can I mount them too?
4)is this an awesome website?

The soviet scope you have there is an early NKVD SVT-40 type scope which then became the standard PU 3.5x. your one seems to be fitted with a SKS type mount.
the other seems to be a Yugo scope
