Two Erkennungsmarken, help.

[gianni59]

Hello.
I would help to understand with certainty what are the military units that have issued these two my Erkennungsmarken.
I did some research and came to these conclusions, but I'm not sure:
1-Luftwaffe Sanitäts Bereichs Fritzlar;
2-Leichte Batteries - Beobachtungs Abteilung 23.
You confirm what?
Thanks in advance.
Giovanni

You were about right with number 1:
Sanitätsbereitschaft der Luftwaffe Fritzlar, that's what I could find for you.
Nice erkennungmarken

I think the second one is Lichtmess-Batterie Beobachtungs Abteilung 23
