Matt,
I have one of the German produced K98k rifles that was reworked by the Yugoslavs after the war. Mine is all original German parts and the barrel appears to be the original barrel to the receiver. The Waffenamts have been removed and the mfg code and date have been removed. The Yugos did a nice job on mine and the rifle is almost 99%. All parts were renumbered during the rebuild and match. The headspace checked great on mine and it shoots 5" groups at 200 yards. If my eyes were better, I think it would be even better. At 100 yards, I can keep them in a 2-3" group. The current Model 48 and 48A that is for sale are great buys! The rifles are in almost mint condition and sell in the area of $180 and worth it. The difference in the Model 48 and 48A is that the Mod. 48 uses all milled small parts and the 48A uses stamped parts for the floorplate, retaining bands, etc. Either of these are gre4at rifles.
I think Ellison's Armory have them for sale. I will attach a link to their site. Good luck on your search and keep me posted, I love to shoot them.
