$125 is hard to beat, for any mauser, photos would tell us more, but I'd say buy it. Provided it's complete, its worth more than $125 in parts alone, so you won't lose any money.
It could still be a Russian capture. The Romanians sent troops to help the Germans invade the USSR.I went to the shop again today, it is infact a Romanian contract rifle with the block looking front sight, the serial is ER 1050xx I have no idea where that puts it as far as a production year but figured it might help all of you help me. The symbol on the top of the reciever is scrubbed and the stock is a smooth beautiful dark red lots of dings and indents from use. They upped the price to $159 but I think I'm going to snatch this one up.
