German NAZI NSFK Lapel Membership Pin-The NSFK, as you know, is the predecessor to the Luftwaffe. Very nicely marked on the back with a stylized “GB”, for Gustav Brehmer, the Ges.Gesch along with the serial number 18837. Very nice detail.
History: Since the Treaty of Versailles officially forbade Germany from building fighter planes of any sort, the German Air Sports Association used gliders to train men still officially civilians for the future Luftwaffe. This air sports organization officially became the NSFK in 1937.
