as k0nr4d said there was a big genocide in yugoslavia, and nowdays there is nobody left, resulting in current population count of 0
regarding ak-47, it is a random engravement.
ak-s didnt had any engravings on their wooden parts (i guess the carving is on the wooden part of the handle), only engraving was the serial number and it was placed on the metal construction of the weapon, wooden parts can be removed and putting engravings on them would be pointless.
biggest yugoslavian weapons manufacturer was "crvena zvezda kragujevac" (red star kragujevac), duro dakovic manufactures trams, and some tanks in the past
