It's Rod Hadfield's Warman Special built in Australia ..... and surprisingly it took some finding. There are so many aero engined cars!
The basis for the chassis is a Packard, and it is a full size version of a model his grandfather built in the 30's.
Rod Hadfield is a prolific car builder - he also built a Merlin engined 55 Chevrolet, and a Fiat Topolino with an 8 litre V12 la France fire engine motor.
