Heer Medical Personnel's Trade Badge

Trade and Specialist badges were introduced at varying times through-out the Third Reich to distinguish EM/NCO personnel who had achieved proficiency at a particular trade, specialty or function. The identifying insignia was most commonly worn on the lower right sleeve of the service or field tunic of qualified personnel.

Pre-1940 pattern insignia made of dark green wool base with embroidered Asklepian in golden yellow to the center. Un-issued example in Close to mint condition. 

Nice exampel!!
