Currently I'm researching the German soldiers who died during the liberation of the nothern part of Noord-Brabant, Holland. For this research I want to have a look in the Vermisstenbildlisten of the German Red Cross. To be able to find the correct pages I need the feldpostnummers of some batallions. I've had a look, but can't find them. Does anyone know were I can find these feldpostnummers, or can anyone supply me with the feldpostnummers of the following three batallions?
Flieger-Ersatz-Bataillon XII
and
Flieger-Ausbildungs-Regiment 53
and the last one is:
Flieger-Ausbildungs-Bataillon 53

I hope anyone can help me.
