Flak ID disc

[juanjo67]

Hello good morning, I would like to have more information about this dog tag. I know it's from an anti-aircraft battery, but I don't know if it can be identified to which part of the German army it belonged. They sent it to me from the United States. I know that A is the blood group. All information is appreciated. All the best.
