Luftwaffe Flight Technical Personnel's (Fliegertechnisches Personal) Trade Badge (Tätigkeitsabzeichen). The flight technical personnel's trade badge was introduced for wear by qualified personnel on 13 May 1935. The badge is nicely machine-embroidered in silver-white linnen on a blue-grey woolen background having a nice black backing cloth and is having a gold cord piping added to the outer edges of the badge. Nice example in good used condition!
