Ok, so I have this tin that I bought at a gun show earlier, but I cannot for the life of me, find the description of the cryllic letters on the box. I will not open the box to check. The sign at the show said Bulgarian, and I don't remember the rest. The main thing that worries me, is that there is a cryllic letter that looks like "III" which I remember being a designation for machinegun ammo for certain types. I don't want to open this stuff and find out I bought machine gun ammo, and lose all of it's value because it is now open. Does anyone have a link to the description of the information on these soldered tin boxes? I would really appreciate it.
