68rs327, I have a similar Yugo K98icon to yours but in U.K. De-activated form. My example has a flat butt plate which is the main visual difference. Can you see any sign of "X" markings on any parts of your gun? My Yugo K98 has a feint "X" near the pistol grip which makes me suspect that Russiaicon may have supplied/sold/gifted some K98s or gun parts to Yugoslaviaicon post war. I'm not convinced that the number on the barrel is a serial number; I suspect that it could be a dated August 1958??? I have never heard of the Yugoslavs removing the serial numbers off the barrels but only off the receivers. I believe that quite a high number of barrels were replaced in the refurb programme including my example. My example has no serial number on the barrel.
