I brought her home today! Squee!
Springfield M1 Garand. Feb 1943 manufacture according to the serial number. Rebarreled with a Danish barrel and brought back in the 50's by the CMP. All matching serial numbers except for the barrel of course. Even the wood has matching numbers to the rest of the rifle. Very nice. I likey. Now to stock up on it's feed.
Edit: According to Fulton's Serial number list, it's a Dec. '42 manufacture.
