Luftwaffe Rank Patch (Dienstgradabzeichen). The patch is showing two so-called 'moustaches' (Schwingen) indicating an 'Unterfeldwebel' or 'Fähnrich'. The two moustaches are executed in white wool and sewn on a dark-blue woolen background. These patches saw usage on the flight-overalls and even on paratrooper jump-smocks. Nice original rank-patch in good unissued condition!
