My records indicate the following:
Kingdom of Serbs, Croats and Slovenes until 1929.
These Mauser usually displayed markings in Cyrillic. The guns made before 1939 also had a chamber-top crest of a crowned shield bearing a double headed eagle, placed on a pavilion of gathered cloth. Products of Voino Tekhniki Zavod (state factory) in Kraguyevac often bore a trademark comprising of BT3 (Cyrillic for VTZ) within a triangle. The chambers of post 1948 weapons had the state emblem of six torches within a circle of wheat ears.
Prior to 1923 the kindom of Serbs, Croats and Slovenes used of Servian M1899 and M1899/07 rifles converted to 7.9X57mm, 7.9mm M24B rifles (ex-Mexican M1912) converted at Steyr in the 1920's and shortened ex-Turkish M90T 7.9mm conversions.
