This is a nice example of a 'Schutzpolizei' Sleeve Eagle (Ärmeladler). This machine embroidered version was to be worn by NCO’s (the German Police had no enlisted ranks). The eagle is embroidered in green on a field-grey woolen background. The name of the city 'Duisburg' is nicely embroidered above the eagle. The eagle has clearly been tunic removed. Stunning original sleeve eagle in very good condition!
