A nice original Black Wound Badge here, unmarked on the reverse. This wound badge has no remaining paint on it's obverse, however it's reverse is still clearly painted black. Signs of wear point to the black being removed from this badge intentionally, which is clear from scratch marks in the arms of the symbol. The marks, however, do not look to have been made recently. Working pin and catch on the reverse.
The Wound Badge (German: Verwundetenabzeichen) was a German military decoration first promulgated by Wilhelm II, German Emperor on 3 March 1918, which was awarded to soldiers of the German Army who were wounded during World War I. Between the world wars, it was awarded to members of the German armed forces who fought on the Nationalist side of the Spanish Civil War, 1938–39, and received combat related wounds. It was awarded to members in the Reichswehr, the Wehrmacht, SS and the auxiliary service organizations during World War II. After March 1943, due to the increasing number of Allied bombings, it was also awarded to civilians wounded in air raids.
