welcome. Im not sure of the year.. Vaugn99 would know. Also what ever mount that is on there will have to be removed. And Id say its only good for making a s.s.r. mocked up sniper..
Its prewar for sure.. s.s.r is short side rail.. go on ebay there are tons of them on there for sale cheap..
not sure.. you might be better off selling it off and just buying a complete repro setup off ebay,,
I concur on the selling it part.
If you cannot remove the bottom rail it will be near impossible to make any conventional mount work due to the location of the rail and the rear focus.
Personally....I wouldnt waste the money on a repro scope...buy a real german scope and go with a repro mount.....heard a lot of bad reviews on the repro crap optics.
My 2 cents..
