Just to test my ability to identify the forced numbers, the area on the bolt handle looks to be scrubbed and the "g" has been partially removed, or I think that's a g. Also the area doesn't have the semi circular pattern and seems to be straight as if someone used a power sander or grinder on it. I hope that makes sense. I'm new to this and seeing if I catching on. Correct me if I'm wrong.
I also noticed there are different fonts of "3" all over the rifle. Was that common on these or is that another flag?
