No kidding, you want to learn about the various Chaps get the Falconer book. It traces the chassis, interior tubs and body designs. It pictures cars from various races. Remember that the car changed from race to race. Part of the enjoyment I get from building copies of old race cars is reading books dedicated to those cars. I don't build great cars like some guys here, but I make copies that I am happy with. I have reference books that have great photos of these great old racing cars and they give me something to shoot for.
Your questions won't bother anybody on here.
