Hi Larry,
You have addressed my comment previously to my full satisfaction

. I have tested my interpretation of zbV on our learned German colleges and they agree with me.
The AM list is not faultless, one of my favourites is Luftnachrichten Dienst translated to Air Intelligence Service, which is an OK translation, but it does not describe the operational function, which was Control, Reporting and Signals Service.
But my small comment does (hopefully) not detract anything from your great effort and piece of work.
kind regards
SES
