Attractive, WH (Heeres) 'tropical-styled', trade- and/or special-career insignia (or: 'Signal Blitz') as was intended for usage by a soldier (ie. NCO) who served within the: 'Pionier-Truppen'

This is a neat WH (Heeres) 'tropical-styled', trade- and/or special-career insignia (or: 'Signal Blitz') as executed in machine-embroidered black- (ie. 'schwarzer'-) coloured linnen as was specifically intended for usage a soldier (ie. NCO) who served within the: 'Pionier-Truppen' (or: simple soldier ie. NCO who served within an engineers-regiment ie. unit) and that comes in an overall very nice- (ie. I deem issued- albeit never mounted- nor worn- ie. 'virtually mint'-), condition. The patch is a non-maker-marked example that shows a nicely reinforced-border and additional (tropical) backing: it does show some minimal age ie. staining simply caused by decades of storage only (as can be seen on the pictures). Simply a nice occasion to acquire a 'virtually mint', 'tropical-issue' ie. DAK- (or 'Deutsches Afrikakorps'-) related: 'Signal Blitz' as was intended for for a soldier who served within the: 'Pionier-Truppen'!
