Steyr & Austro-Daimler

And while I'm still here... :)
Sadly there is no information whatsoever to be got in Austria about the pre-war racing exploits of Steyr and Austro-Daimler. I know they had a few quite spectacular racecars, (von) Stuck sr. drove for them successfully, a few ended up in Britain, but that's just about it. Where can I find out more?? I'd appreciate any hint.

If you drive from Vienna towards the top west side of the country, there's a motorway rest station on a narrow bit of road where the rest station is devoted to the hill climb venue it obviously consumed when it was built. There seems to be a lot of pre war pictures especially in the 'gents'. Maybe some threads there! LOL
