My friend has a 30-06 that he inherited and asked me if I knew anything about it. I didn't. I thought maybe you guys could help. The reciever is samped Carl Gustaf Stads Gevarsfaktori with a crown over a C and a 3 over 64 (3/64 like a fraction). Anybody have a clue what this would be and what it might be worth. He was thinking of drilling it for a scope mount but I told him to wait until I could get some info on it.
