I was looking for a nice 3x9 scope for my target .22 at a gunshow today and I saw a Redfiend with target knobs. I've never seen one like this on a vintage redfield so I picked it up and looked at it and it had RT-6 which looks electropenciled on the bottom of the scope.
About everytime I've seen electropenciling on a scope it has something to do with the military.
What do you guys think? Here are some pics.
