GeeRam,
The Mauser Karabiner 98K logged as a short version of the Gewehr 98 which was recovered when large stocks were found in Bosnia and Croatia during NATO Ops by 1 and 2 PARA in the 90's.
Wanted to add which is a strange anomoly, it is fitted with a grenade holder which is dated and placed to the Battle for Arnhem, with absolutely no more details other than that>
