I did confirm from Century that these are mismatched, arsenal refinished with nazi proofs scrubbed off. RC. So in this instance, the price is pretty high. I'm passing on them.

They actually have a couple other rifles I think I'll get -- Vz24, Steyr M95. And I found a K31icon elsewhere that I think I'm going to get. Nice thing about non-Mauser collecting is there isn't as much forgery, price-gouging, and general shenanigans.

Thanks for all your input!
