Late-war K98k rifle sling 'jwa 4'

A very nice, late-war period leather K98k sling. Of course, the StG44 and G/K43 semi-automatic rifle etc were also designed to accept this same sling. 
 
This example looks to have only been issued for a short period, if at all, and has therefore avoided any oiling. As such, the original leather colour and ricasso cross-hatch pattern is retained throughout. 
 
There are visible remains of the 'jwa 4' marking to the inside surface, signifying production by Moritz Stecher, Lederwerk, Freiburg - during 1944. 
 
It is getting very hard to find such slings in this condition. All it requires is a keeper tab (and maybe some feed, since it is a little dry/stiff, if it is to be fitted to a rifle).
