Can someone please help me identify this Mauser action. As far as I can tell it is a large ring, beyond that im not sure if it is military or comercial. The only markings are the serial number (p-7xxxx) on the left side and what looks like a small clover or star and 231(?) on the bottom of the recoil lug. It is also drilled and tapped. I will have pictures up by tonight. Thanks for any information!
