German WWII NSFK Membership Lapel Pin-This is a very interesting variant; this is in the form of a lapel pin with its buttonhole attachment. This pin shows the Icarus icon of the NSFK on the front. Above him is the script NSFK over his head. Below him is a stem of oak leaves. The reverse of this pin is marked GB for the maker Gustav Brehmer. It also shows the serial number. To the right of this is Ges.Gesch. This is a handsome little pin that is missing from most collections.
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.
