Registration CUV256C actually started life as a Green Line RCL coach in June 1965, complete with twin headlights and rear platform doors. As RCL2256 it was converted to a bus layout by London Transport in 1980, and received an RM type platform following an accident that same year. The model depicts this unusual hybrid in its circa 1991 guise as working for Southend Transport on Service 1 to Southend Central Bus Station.
