A fine original WWII German Kriegsmarine Coastal Artillery breast eagle. Constructed of a machine embroidered national eagle in golden-yellow thread on a dark green field. Unissued condition but does appear to have been attached to a photo album at one point - likely a souvenir from the war. 
 
The Kriegsmarine was the navy of Nazi Germany from 1935 to 1945. It superseded the Imperial German Navy of the German Empire (1871–1918) and the inter-war Reichsmarine (1919–1935) of the Weimar Republic. The Kriegsmarine was one of three official branches, along with the Heer and the Luftwaffe, of the Wehrmacht, the German armed forces from 1935 to 1945.
