This is an zinc-based Polizei ID-disc (Erkennungsmarke) intended for a member within the '2.B./Art.Ers.Abt.251' (Artillerie-Ersatz-Abteilung 251). The ID-disc shows regular usage. The disc also bears the soldier's blood-group (type: 'A') which has been clearly imprinted on the front of the disc. The ID-disc comes in its original Leather Pouch for the 'Erkennungsmarke', complete with original carrying cord. Nice set in good used and worn condition!
