This is a two-part series of articles that ran in the Saturday Evening Post in 1925. They are an autobiographical overview Oldfield wrote with the assistance of William Sturm. I judge some of this material to be inaccurate, not because Oldfield embellished (not that I put it past him), but because I think he simply forgot things.
If you have not checked out MotorSnaps.com, you need to. This Web site has an amazing collection of photos of race cars from the 1920's. A real treat. There is some other stuff on there from more recent years as well.
