Today I purchased this rough condition Gewher scope. I have done a bit of research on these, but I have never seen a case like this one, or a scope with as low a number as this one. The number on this scope is 289. I was wondering if anyone knows what this low number means.
Letters on scope read, EMIL BUSCH A-G BATHENOW VISAR 2 3/4x Gewehr No 289 g
