you see it here in the 1913 Stukenbrok catalog, the new carbine 98 came then to the german army and the old carbine 88 was sold cheap as surplus.

Nr. 7781 is the orignal military carbine - 40 Mark

Nr. 7782 "stalking rifle" is what we could call a factory made sporter 50 Mark, little changings to get a hunting rifle
its probably this gun above

a similar short Mauser 98 is Nr. 7356 here
cost 150 Mark
