WH (Heeres) trade- and/or special-career insignia ie. hand-embroidered signal-blitz: 'Nachrichten-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 bright-yellow- (ie. 'zitronengelber'-) coloured branchcolour as was intended for a 'signals-operator' (or: 'WH-Nachrichtenpersonal') ie. soldier serving within the: 'Nachrichten-Truppen' (ie. signal-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 bright-yellow- (ie. 'zitronengelber'-) coloured and was as such intended for a: 'Nachrichten'-soldier. The patch - that is void of a makers'-designation on its back as more often - shows some minimal storage-age and/or staining only. This example is additionally 'backed' with a piece of greyish-blue-coloured (chees-duck-based) linnen as more often seen. Simply an attractive 'Signal-blitz' that is very hard to be upgraded!
