Hi Norman
I think Roy Lunn's middle name is Charles. The guy I was thinking of was Charles Edward Carrig, who worked on the Mustang prototype suspension with Bob Negstad and Roy Lunn in 1963. He was one of the first guys to use computer technology in suspension design.
I could email Roy Lunn to see if he knows, but not I'm sure if I'll get an answer.
Cheers.
Rob
