When I was trying to solve this puzzle, I found a thread on another website concerning kit cars, which began in 2012 and was posted by a Dutchman called Jerome Wassenaar (his profile doesn't mention a town or city) who built a Sammio-based car with his father. He travelled to the UK to pick up the shell, which may have been to special order with the body intended for LHD. He used an F-Reg Vitesse convertible as the donor car (that's 1969) and he modified the body quite a bit to get the result he wanted.
The finished car has a different registration to the puzzle car, but also has the Mobil decals attached. I wonder whether he had anything to do with this puzzle car?
