Vintage black leather rucksack

Black leather vintage rucksack In great condition. Some wear on the zipper pull (see photo) And a small spot on the bottom of the bag. Drawstring has been replaced. Felt lining on the straps, all grommets, eye holes, and hardware in great to excellent condition. Only tag in the bag is the one in the last photo. Didn’t bring up anything on Google. All I know is the bag is from the Netherlands since original owner is Dutch.
