RARE pre-war K98k leather sling 'K&B Reichsheer 1936'

A very rare early leather pre-war leather sling for the K98k rifle, in good combat used but supple condition. 
 
The keeper tab is clearly marked 'K&B Reichsheer' and dated 1936! 
 
One of only a handful of such early pre-war marked slings which we have seen in over a decade of collecting weapon related items!
