Here is my 1941 dated K31 rifle - I was lucky enough to find one complete with her original sling and a Waffenfabrik diopter set, which was exactly what I needed to shoot her safely and with some degree of accuracy at the range with my 50+ aged eyes.

The rifle was imported to Germany by Frankonia Waffen Würzburg (WWF marking on the barrel).

The walnut stock is not particularly attractive, but, from what I had read, walnut was becoming quite scarce at that time.
