Johnathan, What a conundrum - The caption on the thumbnail is 'Foden C Type', the truck has Leyland and Daf and Foden badges and livery. Change the caption to 'PACCAR Europe' and there you will have it.
A brilliant weekend with sunshine, good company, playing with steam engines and eating some of davidje's cakes.
Thanks to Clive, Geoff and the staff at the Leigh Arms for making it all happen.
