Here are some pics of my 1903 we had talked about earlier. I had the barrel erosion checked and it was near zero! Proofing on the muzzle has SA 9-12 which corresponds with the manufacture year. In the pics, it appears it was reworked at the arsenal. The cartouches are DAL and EHB. There is a chip in the stock on the B. The is a corrugated staple as you can see located right below the tang. The question is....Why would a virtually new action need to be reworked? Maybe to test the strength of the action? Can someone identify the proof marks?
