WH (Heeres) trade- and/or special-career insignia ie. hand-embroidered signal-blitz: 'Pionier-Trpn.'

This is an attractive - and I deem simply never used! - example of a so-called trade- and/or special-career insignia (ie. 'Signal Blitz') as was executed in the black- (ie. 'schwarzer'-) coloured branchcolour onto a (scarcely seen!) field-grey background as was specifically intended for a 'signals-operator' (or: 'WH-Nachrichtenpersonal') ie. soldier serving within the: 'Pionier-Truppen' (ie. army engineer-troops) and that comes in an overall very nice- (I deem never worn- ie. 'virtually mint'-), condition. The patch is neatly hand-embroidered on field-grey-coloured wool and shows no defaults whatsoever. The 'Blitz' is black- (ie. 'schwarzer'-) coloured and was as such intended for a: 'Pioniere'-soldier. The patch - that is totally void of a makers'-designation as more often - shows some minimal storage-age and/or staining only. This example is additionally 'backed' with a piece of greyish-coloured linnen as more often seen. Simply an attractive 'Signal-blitz' that will be very hard to be upgraded!
