WH (Heeres) so-called trade- and/or special-career insignia (or: 'Heeres-Tätigkeits- abzeichen') as was intended for: 'Sanitätspersonal' (or medical orderlies- ie. staff)

I recently found a small bundle holding 15 fully identical patches being all neatly hand-embroidered examples which are executed in bright-yellow- (ie. red and/or black-) coloured linnen on a dark-green-coloured- (and/or smooth woolen-based-) background. All examples are nicely maker- (ie. 'G &H'-) marked on the (neatly reinforced!) backings and all show some minor age ie. minimal staining caused by decades of storage only (see pictures). The pieces have simply never been used and can easily be graded 'mint-/unissued'. As stated above do all 15 insignia-pieces show an additional- ie. 'double'- backing as executed in greyish-blue-coloured linnen. The price is naturally intended per single piece.
