I've seen the all matching number swede's hit the $400 mark lately too. Years ago the non matching numbered ones were selling for around $200 to $225. But now the price depends on what condition it is in too. I was lucky here years ago because Mikey and S.Sumner told me about the quality of the swede mausers and how I should have one they were right.
BTW; That tag looks like a Samco tag too. The quality of the swede mauser depends on when it was purchased from them too. We went thru the bottom of the barrel on the swede mausers a few years ago too. I have heard about them assembling anything they could to sell it too, the snipers were lately too. Make sure you get a 3 day inspection with any unseen purchase over the net too, just make sure you can return it for a refund.
