Uberschube WH (Heer) 'Infanterie-Regiment 313' (WH (Heer) slip-ons for the 'Infanterie-Regiment 313')

This is a nice matching pair of WH (Heer) shoulderboard 'slip-ons' ('Überschube') as intended for a 'Soldat des Infanterie-Regiment 313'. The pair is showing the nicely 'chain-stitched' embroidered regimental numbers '313' in white on a fieldgrey woolen background. The white branch-colour is indicating a soldier within an Infantery unit.
