When I lived in Germany back in the late sixties, early seventies MEOPTA were like truffles amongst my German friends, hard to find but when found, appreciated like gold dust.
They were of course 'Grey Imports' then because of the Eastern Bloc country's restriction on Exports.
I might point out for the 'unaware' that they were not used only for 'Fat pigs' but all manner of other game also.
I have had a few 3-12 x 50 Meopta's and was not aware of any difference between them and my S & B or any other makes that I owned at the time.
There is one critical difference between Meopta and any other scope, apart from the price, and that is eye relief, the Meopta has very little room for variance in the position of the eye.
I have no proof but was told by quite a few German hunters that I had no reason to disbelieve, that MEOPTA has a history of high quality optical lense manufacture, mainly photographic.telescopic or medical, going back to the time before Swarovski.
