Roland,

You are fully right with the concern about the location.

Under the link below the Siebel photo there is another one with the caption:

“COL Robert F. Sink at Zell Am See, Austria, where he had set up the REGT HQ Command Post in May 1945.”

That makes it pretty clear that the location is “Bruck an der Großglocknerstraße” which is the “other side of the meadow” of Zell am See airport.

I assumed that it was “Bruck an der Mur” because that is the only location with “Bruck” where I can prove a Luftwaffe unit during the last weeks of the war.
