'BeVo'-woven version of a WH (Heeres) so-called: trade- and/or special-career insignia as intended for a: 'Nebelwerfer Richtkannonier' (or: qualified smoke-troops canon-operator)

This is a truly very attractive - and extremely rarely encountered! - 'BeVo'-woven version of a WH (Heeres) so-called: trade- and/or special-career arm-insignia (or: 'Laufbahn- o. Tätigkeitsabzeichen'), as was intended for a: 'Nebelwerfer Richtkannonier' (or: qualified smoke-troops canon-operator) and that comes in an overall very nice- (ie. 'virtually mint- ie. unissued'-), condition. This rarely observed badge was a special-career insignia that was specifically intended for a: 'Nebelwerfer Richtkannonier' (or: qualified smoke-troops canon-operator). The patch on offer here is neatly woven in the so-called 'BeVo'-weave pattern (done in silverish-white-coloured linnen on a darker-green-coloured- and/or: also linnen-based background) and comes as stated above in an overall very nice (and IMO virtually mint-/unissued- and/or never tunic-attached- nor folded-) condition (as can be seen on the pictures). The patch shows some minor staining simply caused by decades of storage only. As far as I know are there only a handfull of these rare insiginia known to date. Simply a truly very attractive and rarely encountered: 'Laufbahn- o. Tätigkeitsabzeichen' that was intended for usage by a: 'Nebelwerfer Richtkannonier'!
