Thank you for your clue. You're right, this car is obscure. I thought I knew a bit about 1950s British cars, but this one is new to me.
After much investigation, I have found your puzzle images. The car is a Nordec from 1949, built by the North Downs Engineering Co in Whyteleaf, Surrey. They had obtained sole rights to Marshall superchargers and Ballamy i.f.s. and decided to build their own car to promote these products. This car is the prototype, and was shown to "The Autocar" and described in their issue of 25 March 1949. It used a stretched Ford 8hp chassis, with the s/c Ford 10hp engine. The photo clearly shows the remote gear linkage required.
The magazine were told that the production models would be lower and more sporting, but I reckon they never made any. Georgano mentions the car, but does not give production figures.
