Filled brown leather mapcase marked A. Waldhausen, Köln 1936, Infanterie-Regiment 9

Nice original pre war brown leather mapcase in good, used condition. The mapcase is nicely marked A. Waldhausen, Köln 1936 and features a unit marking for Infanterie-Regiment 9 which is a very interesting unit. The mapcase retains some of its original content; some pencils and a clear mapcase insert. Very nice unit ID'ed filled mapcase which deserves more research!
