Single Luftwaffe FLAK NCO's Shoulder Strap as intended for an 'Oberfeldwebel der Flakartillerie' within one of the Luftwaffe War Schools (Kriegsschule). The shoulder-strap is having the red ('silk-like') piping indicating the 'Flakartillerie'. The strap is having the standard silver-coloured NCO braid attached and the cypher 'KS' indicating a member within one of the Luftwaffe War Schools (Mitglied einer LW-Kriegsschule). The strap comes on its functional tongue. Nice original single shoulder strap!
