As far as I'm aware, this is the only car of this type that I've ever seen. It competed in a Four Lap Handicap Race at the VSCC's meeting at Oulton Park in August 1996.
It's Tony Crowther's 1930 1465cc supercharged Rally NCP. Automobiles Rally produced cars in Colombes, a suburb of Paris, from 1921 to 1933, but was a victim of the economic depression of the early 1930s. The car next to it is Roderick MacPherson's 1953 Cooper Bristol T20.
