Robert Powell?
No.
I was going to say Robert Powell as well but Hiawatha beat me to it.
This is the reason; quote from Robert Powell's website:
"My second project happened by chance. While looking though Motor magazine I came across a story about the late Paul Jameson. He was known at the time for crossing Europe at highly illegal speeds in a 12 cylinder, tank-engined car with a Rolls Royce grille. Even I remember seeing pictures in the Daily Mirror. All rubbish of course; although the car existed and drove it never went 190mph. He decided to correct this by building a second car with the fabulous 12 cylinder, 1750 bhp, supercharged Spitfire engine.
The car was finished, drove and there was a design competition to design a suitable body.
I spent some time doing preliminary sketches then worked on the final design. Once finished I delivered by hand the sketch to the Motor Magazine offices I had the luck to win the competition against quite a few known designers of the time. £10.00 was the prize but the intention to build the design was the reason we all entered."
So your puzzle picture can't have been the winning design? There is a picture of Robert Powell's car on his website and it doesn't look anything like your puzzle photo!
