WH (Heer) Medical NCO's Trade Badge

Wehrmacht (Heer) trade- or special career insignia, as intended for a Medical NCO (Sanitätsunteroffizier Abzeichen). The patch is showing a neatly machine-embroidered Asklepian in golden-yellow linnen on a fieldgrey wool base, the badge is having a silver border indicating a NCO's rank. The badge has a nice grey linnen backing. There is some glue residu on the back, it has most likely been pasted in a scrapbook once.
