This is a German K98 Mauser that was picked up from under a dead German soldier by one of the members of the 506th Squadran 404th Fighter Bomber Group in Normandy France near Omaha Beach in 1944.
The interesting (and disturbing!) thing about this rifle is that it, along with a bayonet, leather ammo pouch, and a P38, was buried in the ground prior to shipping back to the US to try to get rid of the stench of decaying human flesh. The leather ammo pouch still smells foul even after all of these years.
