Wow, what a piss poor investment. Adjusted for inflation, that $3780.00 gun in 1957 would be worth $33,795.00 in today's dollars. So we are looking at a terrible investment over time. Worse I doubt he could get a third of his asking price unless the buyer was blind, deaf, dumb and stupid. Nice prototype White Line recoil pad. It does look like you can see the barrel makers marks and they don't look like Krupp to me. Thanks for the laugh.
