I stumbled across a listing with a pic of a very rare 1950 Tatraplan VW engined streamliner...I had never seen a picture of one let alone seen one first hand...that might be interesting to look at. There is no direct link to it, but it is about the
eighth row down the pictures. I saw it while following a link that had been forwarded to me about
Paul Newman's "Indy VW". You might enjoy looking at that as well, although it has nothing to do with aero packages.
Cheers
P.S. Here is an article about a
Tatraplan that is in better shape.
