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

This is an attractive - 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 des Heeres' (ie. female signals-operator) being a neatly machine-embroidered- (ie. 'BeVo'-woven!) 'variant' on black-coloured linnen that comes in an overall very nice- (I deem never used- nor tunic-attached-), condition. The neat patch is executed in bright-yellow-coloured linnen onto a black-coloured- and/or linnen-based background and shows a (detailed and/or neatly machine-embroidered) 'signal-blitz'-sign. The non-maker-marked patch is not backed and comes as 'straightly cut-off the role' (as can be seen on the pictures). The patch shows some minimal staining (and fraying on top and bottom) simply caused by decades of storage and handling over the years. Moreover, does it show some minimal glue-remains on its back, simply caused by having been glued into an album or scrapbook once. It should be noted that these interesting, 'Nachrichtenhelferinnen'-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', accordingly!
