Wehrmacht (Heer) 'Feuerwerker' Trade- & Special career insignia (Tätigkeitsabzeichen). The Ordnance personnel's trade badge is showing a neatly machine-embroidered Gothic 'F' (indicating Feuerwerker) in golden-yellow linnen on a fieldgrey wool base. The patch is having a nice black coloured cloth backing. Nice example in good unissued condition!
