My father drove for Ely Transport and had in the 60s/7 a mk 5 AEC, CUH @@@B. I went with him several times as a boy, it was a flying machine and could keep up with Scanias which were just coming in then.
About 20 yearslater I was driving from seeing a customer in Llanelli and what do I see going up the long bank on the M48 with a coil on....the same wagon in Prosser colours, at least 30 yearsold!
Prosser at Pontllew used to run old AECs between the tin plate works around LLanelli (Treostre) My dad tell me they used to buy all the old AECs from Ely and Prices and then run them for another 20 years!
