I couldn't pass up this Russian Capture K98k a few weeks ago. The code is rare, only 17K K98k rifles made at Mauser Oberndorf in 1934. Compare that to 260K to 670K in 1939-1944.
It's nice that it has no crossed rifle marking on the receiver ring, given that the code is the main attraction, nor any peened markings. It does have the horizontal serial number on the incorrect Steyr made stock, the dip blue finish of all metal, the electropenciled numbers on bolt and other parts, complete mix of parts numbers and makers, and of course an import mark, all of which are RC indicators.
The bore is very good, which is a bit surprising given it's age and that it ended up on the Russian front, where it was picked up where it was dropped, captured or seized from stores.
