Minimally used, WH (Heeres) so-called: female-related trade- and/or special-career arm-insignia (ie. 'signal-Blitz'): 'Nachrichtenhelferin-Führerin des Heeres'

This is an attractive - I deem just minimally used and actually not that easily found! - female-related example of a WH (Heeres) so-called: trade- and/or special-career arm-insignia 'signal-Blitz' (or: 'Laufbahn- o. Tätigkeitsabzeichen') as was specifically intended for a: 'Nachrichtenhelferin-Führerin des Heeres' (ie. senior female signals-operator ie. female officer) being a neatly hand-embroidered 'variant' on black-coloured wool (and showing an additional twisted, silver-black-toned piping attached) and that comes in an overall very nice- (I deem minimally used- and/or once tunic-attached-), condition. The neat patch is executed in bright-yellow-coloured linnen onto a black-coloured- and/or woolen-based background and shows a (detailed and/or neatly hand-embroidered) 'signal-blitz'-sign. The non-maker-marked patch is additionally 'backed' with a piece of greyish-black-toned linnen (as can be seen on the pictures). The patch shows some minimal staining simply caused by minimal wear and/or decades of storage and handling over the years. It should be noted that these interesting, 'Nachrichtenhelferinnen-Führerinnen'-related insignia-pieces are quite difficult to encounter and can easily be graded 'scarce'. I deem that I have priced this attractive: 'Abzeichen der Heeres-Nachrichtenhelferinnen-Führerinnen', accordingly!
