Reichspost armband WWII German

Reichspost armband.  In the Second World War the Reichspost authority spread out to the Polish areas annexed by Nazi Germany, such as the Reichsgau Wartheland, the Reichsgau Danzig-Westpreußen, and the Polish General Government. In 1941 postal codes were introduced. The Feldpost military mail organisation of the Wehrmacht not only served Army, Luftwaffe and Kriegsmarine service members, but also SS-Verfügungstruppen, Waffen-SS and Reichsarbeitsdienst members in the field, becoming the general postal authority of the occupied territories. Deliveries were more and more affected by the advance of Allied troops from January 1945 on.
