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

This is a truly attractive - and actually rarely encountered! - example of a fairly early-period, WH (Heeres) so-called: trade- and/or special-career arm-insignia (or: 'Laufbahn- o. Tätigkeitsabzeichen') as was specifically intended for an army: 'Festungsbau-Feldwebel' (or: fortification-construction NCO ie. sergeant) and that comes in an overall very nice- (I deem moderately worn- and/or once 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) 'FB'-characters as executed in bright-yellow-coloured linnen. The neatly maker-marked (ie. ink-stamped) patch is nicely 'backed' with greyish-coloured linnen and shows some minimal staining simply caused by decades of storage and/or fair wear. This is actually the early-pattern badge that was quite quickly replaced by a later-war-version (that read: 'FP' or: 'Festungspionier-Feldwebel'). This particular example originated from a larger cloth- and/or shoulderstrap-collection I recently acquired for the web-site. Simply a very attractive, early-period WH (Heeres) trade-/specialist-badge: one the of hardest examples of the extensive series to encounter!
