Two registrations stick in my mind from years back.Bet you can't tell me when I had this one . It was an austin ATW621 and another a Ford Consul WEW 907. And I don't even know the Reg of one I have at the momeny off by heart.
You are not far of yogi. It was a 1935 Black Ford Popular with running boards and a indicator which stuck out of the car when you used it. It also had a tin of oil and a duster in a little shelf in the engine. I do remember the number 390 AHJ. It had one previous owner of Essex Water Works. Now I have a mercedes sports car btw.
