[Revi16]

To start with, the insignia doesn't add up.

The shoulder boards are the rank of Hauptmann (Captain).
The single Gull on the collar (as is - metal) is for a Fahnenjunker (Flight Cadet).
Even if the single Gull on the collar was in bullion with Oakleaves around it or with a Bar under it, it would only be a Leutnant (Second Lieutenant).

FYI - The first word in the second line of the tag may be Fliegerhorst. Maybe some higher-rez pics of the tag from different angles would help.

My first impression is fantasy piece.
