Reichsarbeitsdienst Mützen Abzeichen 1938. It is constructed out of a die struck aluminum-alloy base that has been silver washed and contains black and red paint work. The obverse features the RAD emblem, which consists of: a black mobile swastika in front of a spade shovel head (that is outlined in red) and is above two outward pointing wheat sheaths. The full back reverse is maker marked "Ges. Gesch. RADJ 37” and possibly has some other markings, but they are difficult to make out due to contact wear over time. Unfortunately both prongs are missing. It measures 1 ¾ inches wide by 1 ½ inches tall. A lovely item!
