WH (Heeres) so-called: trade- and/or special-career arm-insignia as was intended for a: 'Festungspionier-Feldwebel' (being a neatly hand-embroidered variant mounted on darker-green-coloured wool)

This is a truly attractive - and actually rarely encountered! - example of a WH (Heeres) so-called: trade- and/or special-career arm-insignia (or: 'Laufbahn- o. Tätigkeitsabzeichen') as was specifically intended for an army: 'Festungspionier-Feldwebel' (or: fortification-construction NCO ie. sergeant) and that comes in an overall very nice- (I deem never worn- nor tunic-attached-) condition. The neat patch is executed on a darker-green-coloured- and/or woolen-based background and shows the (detailed and/or neatly hand-embroidered) 'FP'-characters as executed in bright-yellow-coloured linnen. The non-maker-marked patch is nicely 'backed' with black-coloured linnen and shows some minimal staining simply caused by decades of storage only. This is actually the later ie. replacement version for the early-pattern badge (that read: 'FB' or: 'Festungsbaufeldwebel'). This particular example originated from a larger cloth- and/or shoulderstrap-collection I recently acquired. Simply a very attractive WH (Heeres) trade-/specialist badge: one the of hardest examples of the extensive series to encounter!
