Mine has good numbers (600+) of all sorts. A few autographed, one by Moss, "My Favourite Motor Racing Stories", personally notated bok on the Pantera by Wallace Wyss, apparently the most valuable is the English language version of Orsinis "The Scuderia Ferrari" (which I had no idea had any value at all until perusing Eoin Youngs site) Most reffered to; Costin/Phipps Sports and Racing Car chassis design" and "High Speed Low Cost"
