A very fine and early German "Kampfgenossen u. Kriegerverein" (Comrades-in-arms and warrior club) membership badge here from the city of Rellingen. Rellingen is located 10km northwest of Hamburg, which is where the maker of this badge was located. Enamel has minor damage at the low-center of the badge. Still displays beautifully. Working pin and catch to the reverse with an overstamped but clear maker's mark. Rare badge for sure.
