It is likely a Czech made k98 that was refurbished in yugoslavia with a yugoslavian replacement barrel. It is what they call a m52C. That N looking stamp in the triangle on the barrel is a proof stamp from Enterprise 44 state arsenal (later Zastava) pretty cool piece of history! Most of these were repaired after ww2 and put into storage while domestically produced m48 mausers or older Yugoslavian m1924 mausers updated to the k98 pattern were issued out.
Thanks for that information, I really appreciate it. I've owned this gun for a while and have been puzzled for a while. Thank you again. I have also uploaded more pictures if you're interested in looking at those.
I own a bunch of milsurp but a few of my favorites are my Lithgow smle 1942, Argentine 1909 engineer Mauser carbine and my newest favorite, my Swiss K11... It's a special rifle with a troop tag and the most accurate I own.
