From a different era, 4107 (PTW110) was seen at an early Hillingdon Showbus boasting a rare Queen Mary style bodywork with exposed radiator on its Bristol L6B chassis.
So rare are exposed radiator Queen Marys that if there was not the photographic evidence it might have been a figment of the imagination. It was reassuring nearly forty years later to find 4107 in excellent health and fittingly accorded a prime position in the 2011 display at SHOWBUS.
