tropical ties to ID

[Zeller]

I've recently got these 3 ties from a larger lot found in Austria.
I know for sure that some have been sold as DAK ties by a known dealer but with some disappointment when I posted them elsewhere I did not get a positive ID.
It looks like nobody know exactly what they are, someone suggested early SA/NSDAP someone tropical Luftwaffe.
I ironed one to show that they are not so sloppy as they seemed in the find picture. Any idea?
