Stefano, first of all: many thanks for your work with all this!
Please do not take anything I write below as a critic,
just let me clarify a few things as I understand it.
To assign the German hymn for Austria blue (code: AQ) is wrong for this reason:
In World War two Austria didn't exist. it was erased from the maps.
It was part of Germany and named "Ostmark".
The name Österreich (Austria) didn't exist anymore and was wiped out
even on the maps. ie Niederösterreich (lower Austria, one of the nine states in Austria, where some
of my ancestors were and are from) was named: Niederdonau (lower Danube). See
here.
This means: when someone does a mission/campaign for an "Austrian" pilot
fighting in WWII (ie Walter Nowotny etc) then this missions has to go into
DE (German) folder in missions/campaing folders. With stock DE hymn, emblems,
ranks, awards, flag as you use it for "German" pilots of WWII.
Austria blue (AQ) is just the duplicate of Austria red (code: AT) wich has the modern
Austria hymn and Emblem. And so should have Austria blue..
But: we could use at least the emblem of AT, AQ for the Austria Luftwaffe wich
existed from 1936-1938 a it shares the same emblem with modern Austria.
But then the hymn should be different, should be the old Haydn "Kaiser" tune
but with a different text.
This was the Austrian hymn from 1929 to 1938.
Be aware that its the same Haydn tune the German used and use, but with another text !!!
