Three erkennungsmarken, help.

[gianni59]

Hello to all.
I need help to understand the military unit well that he uttered these my two aluminum erkennungsmarken and know if it is good the third EKM.
The first EMK bearing the words: "5./Ob.d.L." Markennummer 97. I'm not sure if it's "Oberkommando der Luftwaffe" or "Oberbefehlshaber der Luftwaffe" and I would like to know what the military unit 5./.
The second EKM has the words: "SCHW.E. & A. BTL.36 ". I do not know if it means "Schwere Flak Ersatz Abteilung", "Schwere Artillerie Ersatz Abteilung", "Schwadron" or even more.
The third EKM, the strange and aluminum form, says "Flieger Technische Vorschule D-Alten (Dessau-Alten)", the year 1940, the markennummer 8161. I I've never seen so. I've paid a few euro by a Russian merchant.
Thank you in advance for the help that you will give me.

The bottom tag is probably for equipment or a tool case. The 8161 is the field post number for:

The top disk (as far as I can tell) is:

Oberbefehlshaber der Luftwaffe - 5. Abteilung Fremde Staaten

Not sure what this group did exactly but it is the "5/Oberbefehlshaber der Luftwaffe" technically.

Middle disk is "Schwadron Ersatz und Ausbildung Battalion 36" Squadron Replacement and training Battalion 36. Unfortunately I cannot find any reference to that unit.
