Very cleverly written by Framptons - click on the documents on line link, then view plans and documents near the bottom to access the links, then click on the file, its near the bottom letter to RBC10.... dated 18th October. Its quite an interesting read and just shows how these things are put forward.
Interesting twist on things by Framptons! Some of the sites they mention wouldn't entertain BriSCA F1 in a million years. A few factual discrepancies with their history lesson re Coventry Stadium too, but interesting as you say, to see how these things are put together.
