Here is a peculiar flag with two different patches: on one side, Nachrichtengefolgschaft 1/531, and on the reverse, Motorgefolgschaft 1/531 Linz Südost Oberdonau.
Is this correct, or has someone been tinkering with it?
All added to the list apart from the 531. I can't think of any logical reason for why the flag looks like that. One of the panels must have been added at some point so I'm going with "messed with".
