New information I found out about Josef was that he was in the SA-Gruppe Nordwest Hilfswerk from 1935 until 1938 when he got moved to SA-Gruppe Hochland.
Some background on Sa-Gruppe Nordwest Hilfswerk-
Following the disband of NSDAP in Austria, a number of SA members flew in Germany to form the "Austrian Legion" (Ost. Legion)
this organisation took name of Hilfswerk Nordwest until Anschluss
