Edit: When i research internet I found that this plane, he was probably belonged to Seenotstaffel 6 or Seenotdienstführer/Lfl. 6
Cant Z.506 Italy Q8+X3 Seenotstaffel 6 or Seenotdienstführer/Lfl. 6
and second
Cant Z.506 Italy Q8+B8 Seenotstaffel 6 or Seenotdienstführer/Lfl. 6
but I didn't found the confirmation.
I apologise for the mistake

Cheers . Piotrek
