I recently bought my first and only all matching k98 from my good friend Dave for $2000.00. It was sent via mail from Germany by a veteran in 1945 who recently passed away in Duluth, MN. The rifle is in like new condition. It retains 98% of it's original finish with only a few corrosion spots from age, and no residue of any kind was found within the reciever or barrel (probably unfired since proof testing). Aside from a dent under the forearm (looks like from banging against another rifle barrel), some corrosion spots pushing the red primer off a couple areas on the inside surface of the buttplate, some scratches and bluing worn off the sight hood, and some phosphate wear to the bolt from the bolt being worked, the gun appears like new. It's impossible for a rifle to be completely blemish free after 64 years under ordinary storage conditions. The waffenamt on the right side of the stock is hard to see only because the stamped area has not accumulated dirt or oil, so there is no contrast, making it tough to see in detail. The wood is not sanded smooth, and retains a fresh cut texture and displays the stock cutting tooling marks. Minimal handling scratches and finish wear. Original sling has an unexplained 1-1/2" long knife cut extending from the third keeper hole. A rare glimpse at an almost untouched late war rifle off the production line.
