I just bought a Yugo M48 for $125, and was wondering if anyone could help me get some info. All numbers match, on the right side of the barrel are W 15506, and has a stamped magazine plate, but other than that, there are no other markings. The stock has been run through the ringer, but I think I can repair and refinish it. I would mainly like to find out year of manufacture. I could post pics, but there isn't really anything to take a pic of.
