Mystery mark on unrefurbed 1942 Tula 91/30.
This is an unrefurbed 1942 Tula that Im giving to my brother for Christmas. Very nice condition, wartime wood, and not import marked! However, there is a marking on it that I have never seen on one of these. Right above the first 6 on the serial number is a pretty large 6 (or 9, could be either) It has almost been rubbed off, I have tried taking a hundred pics of it, but it wont show. Does this sound familiar to anyone? Would like to hear some thoughts!
