Aluminum WH (Heer) ID-disc (Erkennungsmarke) as intended for a member within the '11./J.R.21' (Infanterie-Regiment 21) which took part in the invasion of Poland, Luxembourg and France. The disc also bears the soldier's blood-group (type: 'A') which has been clearly imprinted on the obverse of the disc. The disc is in uncleaned condition as found. Nice original ID-disc in good used condition!
