Hi Martin,
The body was made with an English wheel, various hammers and a buck, just like in the old days. If you are serious about pursuing metal shaping, I would highly recommend taking the class taught by Wray Schelin at Pro Shaper. I actually made the hood for this Cobra while taking Wray's 4 day class and I have attached the link showing the process. It is well worth the money and it is an awesome experience:
