German WWII NSFK Collar Tab-This is made of a blue badge cloth with the early silver metal NSFK Insignia on the front. The propeller and wings retain the majority of their silver finish. There are a few spots of discoloration and a few moth bites. The buckram stiffener can be seen on the reverse. Overall, this is in good condition.
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.
