Minimally used, WH (Heeres) so-called: female-related rank-insignia (ie. rank-chevron or: 'Winkel'): 'Nachrichten-Oberhelferin 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: rank-insignia (ie. rank-chevron or: 'Winkel'): 'Nachrichten-Oberhelferin des Heeres' as was specifically intended for an: 'Oberhelferin' (ie. senior female signals-operator) that comes in an overall very nice- (I deem minimally used- and/or once tunic-attached-), condition. The neat - and as to be expected somewhat smaller-sized - rank-chevron shows a single 'chevron' as to be expected and is executed in bright-yellow-coloured (typical) braid and is mounted onto a black-coloured- and/or woolen-based background (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-Nachrichten-Oberhelferinnen', accordingly!
