Aluminum Luftwaffe ID-disc (Erkennungsmarke) as intended for a member within the '3.Abt.Flak-Rgt.9 13. Bttr.' (Flak-Regiment 9 "Legion Condor"). The disc also bears the soldier's blood-group (type: 'B') which has been clearly imprinted on the obverse of the disc. Nice original ID-disc in good used condition!
