Hello Mick. You refer to a book you are doing on the "Embassy Hill GH2". I expect that refers to Graham Hill, and remember that Embassy cigarettes was one of his sponsors, 'back in the day". Was the GH2 a separate car that he created, or was it a "sub-model" of his factory ride, which at the time I believe was one of Colin Chapman's creations, i.e. a Lotus? From the late 1950's to the 1980's, I was a freelance racing photo-journalist (including as a contributor to Autosport), covering many races in Canada and the U.S. I still have all my historic photos from those years, and depending which car you are referring to, I may have some pics of it. You can see some of my work in my recently self-published book at my website = www.lionelbirnbom.com. Good luck with your project. Best regards, Lionel.
