I take it that wasn't the Hamburg Pa store. They got people in there who thinks any military weapon is gold and put stupid insane prices on them. Like $3000 garands and m-1 carbines. But what kills me is the people who go in there and buy them.
I was equally lucky 4 years ago on this score. Got a 1944 Russian TT33 all matching for $190 at a estate auction because they called it a Romanian Tokarev or some nonsense like that. It probably scared people because It was missing a grip panel and the other grip panel was for a Polish TT. I got it sorted with original WW2 grip panels from Russia.
I cannot imagine doing this at a Cabela's though. They usually are not that sloppy and the pendulum goes so far the other way it is comical at times.
