A very nice original WWII German Heer (army) Artillery Gunner's proficiency trade badge. This one looks to have been removed from a photo album at some point. Displays beautifully. 
 
From 1921 to 1935 the name of the German land forces was the Reichsheer (Army of the Empire) and from 1935 to 1945 the name Heer was used. The Heer was one of two ground forces of the Third Reich during World War II but, unlike the Heer, the Waffen-SS was not a branch of the Wehrmacht but was a combat force under the Nazi Party's own Schutzstaffel forces. The Heer was formally disbanded in August 1946
