Luftwaffe Obergefreiter's Rank Chevron (Armwinkel). The Luftwaffe introduced a series of three rank chevrons on 4 March 1938 for wear by the enlisted ranks of Gefreiter, Obergefreiter and Hauptgefreiter with one chevron indicating the rank of Gefreiter, two chevrons for the rank of Obergefreiter, and three chevrons for the rank of Hauptgefreiter. These chevrons were worn on the upper left sleeve of the Service Dress tunic, the Flight blouse and the Greatcoat. The chevron is executed in grey Luftwaffe cloth and is showing two bands of silver-coloured NCO braid indicating the rank of 'Obergefreiter'. The insignia is showing a nice backing material. Nice example in very good condition!
