Help with German - two airmen's names

[Adriano Baumgartner]

Good night to all members.

Could someone who is familiar with the German language help me identify the two names on the back of this photograph?

One is a Leutnant Hy or Ky??
The other is Fw Gär ???

My gratitude for any help

Leo,

The number of beers am owing you is growing up! If the pandemic do pass and am able to go to Germany, I shall pay you those beers, believe me!

Without you and other members, who knows German language, and are able to decipher what is written behind this kind of images, it would be impossible for persons like me to know what is written....

Do have no words to express my gratitude.

Adriano

I suppose you don't know what German flying unit that these two German airmen belong to?

Edward,

Indeed, there is no date, no unit recorded on the back and no joy either on the front side of the picture...

Hayduk appears only as a Leutnant (A2) in the huge DE ZENG (and all) Files.

Regarding Fw. Gärtner, I found an Uffz Gärtner at 3(F)/122 but surely not the same person...

So the clue to the unit (I suppose it is an Hs 126 unit) may be Hayduk's full fille or register...
