I seem to recall that this car is one of the J2s converted to J3 spec by the factory. I inspected this car, in 2013, as registrar. The then owner was Mr Richard Springford.
It was still owned by Richard Springford in 2016 when I was in touch with him to try and persuade him to bring the car on the Ulster Tour, without success unfortunately. Here it is at Ballybannon in 1933.
