Another car by Ian Headon?
It's difficult to date and name this car (if I'm correct in my identification). According to my source it was styled after a car from 1958, and then the source adds that he built trials cars between 1960 and 1964. This car was definitely in storage from 1964. I believe it was built c.1960.
His trials car was named IRH2 which makes no sense, because he'd already built 2 cars by now, a Microplas-bodied Ford special, and this puzzle car. He built 3 trials cars altogether, and then his autocross sports car was named IRH7!
If this is a Headon car, it had a Ford s/v engine, Wolseley Hornet gearbox, Austin back axle, and bits from a Morris Minor. The body wasn't GRP as usual, but hand-beaten aluminium.
