The present object is a single shoulder board of the National Socialist Flyers Corps (NSFK) for the ranks of Sturmführer to Hauptsturmführer. This sewn-on rank insignia represents an important aspect of the paramilitary organizational structure of National Socialist Germany.

The NSFK was founded on April 17, 1937, through the merger of the German Air Sports Association (DLV) under the leadership of Major General Friedrich Christiansen. As Corps Leader of the NSFK, Alfred Baeumler served from 1937, later succeeded by Colonel General Bruno Loerzer. The organization primarily served for preliminary aviation training and was intended to recruit and train personnel for the newly established Luftwaffe.

The rank structure of the NSFK was closely modeled on the SA and used similar rank designations. The Sturmführer corresponded to a middle leadership rank, comparable to a lieutenant in the Wehrmacht. The Hauptsturmführer was the next higher rank and corresponded approximately to a captain. These ranks typically led smaller units and were responsible for practical training and organization at the local level.

The shoulder boards of the NSFK were worn on various uniform variants according to the uniform regulations. They served for immediate identification of rank and organizational affiliation. The sewn-on shoulder board was directly stitched onto the uniform, in contrast to removable shoulder boards that were attached to sliding loops.

The typical design of such NSFK shoulder boards for the mentioned ranks consisted of a basic color scheme according to the branch or function, supplemented by specific rank stars or pips. The coloring and material varied depending on the type of uniform: service dress, walking-out uniform, or special occasions.

The NSFK was divided into various sections, including powered flight, gliding, model aircraft, and air raid protection. The organization reached a membership strength of approximately 1.8 million people by 1944. Practical flight training took place at numerous airfields throughout the Reich territory and in occupied territories.

During World War II, the NSFK gained increasing importance for the replacement training of pilots and technical personnel. Given the high losses of the Luftwaffe, training programs were intensified. NSFK units were also involved in various auxiliary services, including courier flights, wounded transports, and other supporting activities.

The uniforms of the NSFK followed strict regulations laid down in several uniform books and ordinances. The correct wearing of rank insignia was mandatory and strictly controlled. The present shoulder board shows light signs of wear, indicating actual use during active service.

After the unconditional surrender of Germany in May 1945, the NSFK, together with all other National Socialist organizations, was dissolved and declared illegal by Control Council Law No. 2 of October 10, 1945. The possession and wearing of uniforms and insignia were prohibited.

Today, such uniform items are the subject of historical research and military historical collections. They document the complex organizational structure of the Nazi regime and the role of paramilitary organizations in the preparation and conduct of the war. The state of preservation with light signs of wear makes this specimen an authentic witness to the period from 1937 to 1945.
