Last stamps of German Reich, commemorating NSKK and NSFK:

 

The National Socialist Motor Corps (German: Nationalsozialistisches Kraftfahrerkorps; NSKK), also known as the National Socialist Drivers Corps, was a paramilitary organization of the Nazi Party that existed from 1931 to 1945. The group was a successor organization to the older National Socialist Automobile Corps, which had existed since the beginning of 1930.
The National Socialist Motor Corps was the smallest of the Nazi Party organizations and had originally been formed as a motorized corps of the SA. In 1934, the group had a membership of approximately ten thousand and was separated from the SA to become an independent organization.
The primary aim of the NSKK was to educate its members in motoring skills. They were mainly trained in the operation and maintenance of high performance motorcycles and automobiles. In the mid 1930s, the NSKK also served as a roadside assistance group.
With the outbreak of World War II, the National Socialist Motor Corps became a target of the German Army for recruitment, since NSKK members possessed knowledge of motorized transport. Most NSKK members thereafter joined the regular military, serving in the transport corps of the various service branches. In 1945, the NSKK was disbanded.

 

The National Socialist Flyers Corps (German: Nationalsozialistisches Fliegerkorps; NSFK) was a paramilitary organization of the Nazi Party that was founded in the early 1930’s during the years when a German Air Force was forbidden by the Treaty of Versailles. The organization was based closely on the organization of the SA and maintained a system of paramilitary ranks closely associated with the SA.
During the early years of its existence, the NSFK conducted military aviation training in private airplanes. When Nazi Germany formed the Luftwaffe, many NSFK members transferred. Because NSFK members were also Nazi Party members this gave the new Luftwaffe a strong Nazi ideological base in contrast to the other branches of the German military, who were comprised of "Old Guard" officers from the German aristocracy.
The National Socialist Flyers Corps continued to exist after the Luftwaffe was founded, but to a much smaller degree. During World War II, the NSFK mainly performed air defense duties such as reserve anti-aircraft service.
