Thanks. After the first two were air-cooled, my hopes were up for the 1949 Volkhart-Saggita V2. Similar to the Porsche Type 64, but it carried 4 passengers. Two examples built, and it was re-tested in a modern wind tunnel.

Nice. However, I tried to feature in that chapter of the book only the cars I'd seen in the flesh and photographed. (That wasn't the case with all of them, but nearly all of them.)

5:40 — What's the chance is was a mud puddle that cleared the lower valance?

I was led to believe that the reason for a separation edge is so that in gusting side-wind conditions the separation edge doesn't move fore and aft on opposite sides. That could produce a small wag-the-dog effect.

I doubt it was a puddle - would have left dirty water marks.

Yes, separation edges can also be used to held improve stability (page 178 of my book).

My copy of the book arrived yesterday and unfortunately insomnia helped me through the first 40 or so pages last night. Really enjoying the read, or should I say read and study and ponder. Its a great book, lots of information but written a level where I could let some of my friends borrow it.
