I need a little help to possibly identify this rifle and exactly was I have. This was an attic find and I'm not up to snuff on Mauser rifles. It has dou 44 with Nazi eagles stamped on barrel and bolt. Every serial number all the way to barrel channel in the stock match. It has to cuts in the stock they might be duffle cuts but not sure. What do I have and what would be an approx. value? thanks in advance
