Excellent video Clive. John Roberts turned me on to this one recently. There is some nice color footage from the 1930s. It's rare to see something like that.
One of my favorite parts is when the driver, I forgot the name now, at the German GP is drenched in gasoline. I couldn't believe he drove away after that. I'd have jumped out of the car and tore my clothes off and then started screaming, "Spray me off! Spray me off!" I'd have been immortalized as the driver who tore all his clothes off in the middle of the German GP.
I think I'd have rather driven naked than soaked in gasoline.
