I'm giving Allan_L and D-Type a point each for identifying the name.
Treated as solved now as most of the information has now been solved.
The Vice-Consul was one of two identical sports racers built in the early 1950s by (I think) G.N. Hennessey on a Ford chassis using a Ford Consul engine and a MG gearbox.
By the way, the car in the background (No. 69) is Roy Clarkson's Morgan Saloon.
