Hello, I am the current owner of 2YKM; unfortunately not living in the UK, I had to abandon the registration on the car, but it is still active reg and could come back on the car if one day it is relevant.
I am sure you know that the car at the time of the picture was Sayer’s ownership, only owner until 2014. May be they took the picture but Ted could say.
What is Crystal Palace show?
