Luftwaffe Officer's M43 Cap (Einheitsfeldmütze M43 für Offiziere). The Luftwaffe M43 field cap was introduced for wear by all ranks on 27 September 1943 as a replacement cap for all other field caps then in use. The design of the M43 field cap was based on the earlier M42 overseas cap (Feldmütze) and the Mountain Trooper’s Mountain Cap (Bergmütze) with minor variations. The standard issue M43 field caps were constructed of Luftwaffe blue-grey wool. The cap is having grey-coloured rayon lining material, it is nicely marked with RB.Nr. '0/0501/0016' and it is size '57' marked. The cap is complete with an original period hand-applied Luftwaffe trapezoid. The cap has been period upgraded to an officer's rank by adding a leather sweatband and silver piping along the crown of the cap. The cap is in good worn condition, see photos. Luftwaffe Officer's M43 caps are very hard to find. Nice original cap!
