Hello. I just got this brand new book on Durant and Sloan and it is fantastic. Really informative and the most reveling of any of the Durant books. Much more detail and inside stuff. The author a Mr. William Pelfrey was allowed to go through all of Durant’s papers at Kettering University and all of the Durant Sloan papers at GM. The book has 12 pages of very good glossy pictures and 313 pages total and just released this year. List price is $27.95 hardback and there is all kinds of them on Amozon.com books for $8.40 and $3.79 shipping a real steel. Just enter Durant Sloan. A must read. I just ordered one for Bob Krause as he doesn’t have a computer. Later Lance
