HI
Thnx alot HAMmeR.
I've been to your website and must say you've done exelent job there.
The reason I want the ring sizes is for my gunsight. I fly german planes and use only german sights; the Revi types. I've got this sight called revi-12d (or something close to it) and it has bunch of "tick" marks.I have no clue what range or wingspan they are set-up for. If you hear anything about those rings please make sure to let me know,would you? In meanwhile I'll try to track down the guy that made those sights and see what numbers he used.
Thnx again.
!S! McQ
