Simmering and Austro Daimler

[Toma]

Hello all!
In former Yugoslavia there were few test drives of the DMUs in the late ‘30s. As far as I know, Malaxa, FIAT, Breda, Ganz, Simmering and Austro-Daimler DMUs were on test or presentation drives.
Now; I am interested if there are any details about the Austrian DMUs (Simmering and Austro-Daimler) in Yugoslavia – which DMU’s were on tests, when etc..?

Thnx very much!
