Hi Mark,
there are a few pics in the history gallery on the website of
Austro Daimler.
just click on "Flugzeuge"
[sorry, it even appears much smaller than seen]
I believe this one shows the 160 hp aero engine.
Actually the enlargement tool doesn't work, but you may ask the people of the association. I think they could help you with further information.
There is also a walkaround of the 150 hp Austro-Daimler at the Vienna Technical Museum :
Austro Daimler 150HP aviation engine at Idflieg - World War I Aircraft - Museum Walkarounds.
Cheers
Aquilius
