This is a nice matching pair of WH (Heer) Shoulder Strap 'slip-ons' ('Überschube') as intended for a 'Soldat des Pionier-Bataillon 179'. The pair is showing the nicely 'chain-stitched' embroidered regimental numbers '179' in black on a fieldgrey woolen background. The black branch-colour is indicating a soldier within an Engineer unit. The pair shows some minor traces of years of storage. Nice pair in good unissued condition!
