Delivered new to United Breweries in December 1961, the company becoming Charrington United Breweries in 1962 and Bass Charrington after merger in 1967, this P.166 was pwfu at Leeds-Yeadon in early 1972. It was originally painted in a basically white c/s but during the Charrington United period it wore an unusual bottle green and orange livery before changing to the final version seen here.
