Hi, DWS1117 and SDC,
The rifle started out as a VZ-24 ("Vzor" is Czech for "Model"), made in the 1920's or 1930's in what was then Czechoslovakia. Many of these were bought by Yugoslavia at the time. In the post-WWII period, Yugoslavia undertook a program to standardize their rifles, which were rather a mixed bag, even though most were based on the Mauser 1898.
That rifle was reworked in Yugoslavia in or around 1947; the old Czech markings were removed and replaced with the Communist crest (the flaming torch), the rifle was refurbished and reblued, and given a new designation, the M 24/47. A year or so later, Yugoslavia began production of its own rifle, the Model 48, which appeared in quantity on the U.S. market a couple of years ago. They are good rifles, but not as good as the VZ-24, reworked or not.
Just FYI, the Model 48 (the Model 48A has a stamped floorplate) is sometimes sold as a "K.98k", with stories about its use in WWII. It was not a wartime rifle, was not used by the Germans, and has little historical value. The receiver is not even a standard Mauser 1898, although the VZ-24 is.
