I just ran across this thread while doing a search for "Sieben & Skinner cobra". The reason I began searching: My grandfather (Harry Skinner) is the "Skinner" referred to, on the side of the car. The car was based out of Kansas City mo. Stories of this car have been in my family since I was a kid. I believe the car was owned and driven by Tom Sieben and maintained and tuned by my grandfather, Harry Skinner. I have pictures of this car on the track at Kansas City International Raceway from the summer of 1973. I will try to get them dug out and posted sometime this weekend.
