Had a couple of Tasco 3-9?? x50 which were so masked that they allowed less light through than a x40!! Like looking through a loo roll. nikko sterling did occasionally do a nice scope.
Mounts! They were so very terrible in the 80's. Apel and some Apel type (Hilver??) can work but it was Sportsmatch that finally sorted it if a bit agricultural and beefy. At least they don't turn red but then they don't come gloss like Apel does.
I believe that I.J. sits on a pile of Apel and other desirable steel mounts like some dragon
Like hens teeth to find and then there were different models for HW, BSA and FWB/Omega!
Its a challenge!
