OK...Question time...Did this device ever have ambitions to be a Grand Prix car ?
Although it looks as though it might have an MG engine.....so probably not.....
Body shape appears to be from 1952 or thereabouts. Is it the original ?
Morning Willie. I admire your perseverance, and to repay this I will provide some answers which may or may not assist with a solution.
It was never intended to be a GP car. It does not have an MG engine, but it is powered by a motor from the same "combine". It was built a couple of years after your guess and I believe the car still carries the bodywork from that date.
Try working out the country of origin..........
