It was 1 in the morning when I wrote my reply above so here's a little more background.
As I was saying, the austrian Hitler Youth movement was illegal between 1934 and 1938. Back in the Reich that same period saw the abolishment of the
Oberbann and the introduction of the single shoulder strap for the DJ so by the time the Hitler Youth movement in Austria was being rebuilt and incorporated into the Reich structure after the Anschluss in 1938 things had already been formalised. All DJ boys wore the same rune patch (the old Oberbann 1 colours of white on red) and a single strap with the Jungbann number.
Prior to the abolishment of
Gebiet 22 Deutsch-Österreich in June 1934 however, its structure had been the same as any other Gebiet and there were three Oberbanne in Austria.
As Darin says, it won't be difficult to find a DJ strap for one of the austrian Jungbanne and even less difficult of course to find the matching rune patch as it's the standard white on red.
Just a quick one on my Bann lists: the DJ units are not seperately listed because they of course had the same number as the corresponding HJ, BDM and JM units for the majority of the TR period. So, if you are looking for the correct Gebiet for a DJ Jungbann just look for the HJ Bann number and the Gebiet shown for the Bann will be the same for all other formations.
Bann 55
Jungbann 55
BDM-Untergau 55
JM-Untergau 55
All of the above wore the same triangle and the HJ and DJ the same number on the shoulder straps.
