Ok guys here it is. My dad just bought an M1. It's S/N is 1,339,xxx.
The strange thigs is that the 2nd 3 looks like it has been ground off and the restamped again as a 3. none of the other #'s have been touched. It has a Winchester reciver with correct drawing # and correct Winchester barrel plus some mis matched parts. Any ideas?????
Puzzled!
