It's a Jaguar Byfield from 1952
Very good mekubb.
How did you manage to find that one, especially as the answers given by SACO were not entirely accurate?
Although of course this is based on a British car it was built by Cliff Byfield in Australia, so is technically an Australian car on a British base rather than a British car.
As far as I am aware there is just one single picture of it (this one) on the Internet (well, 2 now as it's on the AP site).
