KuK leather map case ?

[PanzerVI]

Good evening esteemed gents

Came across this leather map case which by chance had 2 folded maps inside (brought a smile tbh) and was wondering if someone could shed some more info as I mostly collect WW2 german-hungarian items. The snap buttons are the only ones bearing a stamp PRYM (which I usually see on WW2 german canteens wool covers) but other that nada. Leather is pretty much ok with some cracks here and there and the plastic is in astonishing condition.

Cheers
