German NSFK Glider Pilot’s Crash Helmet-This is a rare and desirable black leather crash helmet with fully padded sides, and multiple grommeted ventilation circular slots. This has a black leather chinstrap which is still fully functional and a short black leather brim. It also has the neck flaps and ear flaps along with multiple adjustment snaps, to accommodate the size and comfort of the wearer. The size 56 interior is a ribbed purple cloth material, and is maker marked Gustav Vogel. It has a brown leather sweatband. This is an outstanding example from a condition standpoint, and these are not often encountered!
