I took this photograph at the Trans Lancs Historic Vehicle Rally in Heaton Park, Manchester in September 1993.
It's not listed in the programme of the event, but it's a 1934 AEC Regal with an English Electric body from a 1933 Leyland Tiger. Chassis number 6621547 was originally a Beadle bodied petrol engined coach operated by W Salisbury & Sons of Blackpool. It was later given a 7.7 litre AEC diesel engine and the English Electric body and used as a driver training vehicle by Ribble Motor Services. In the 1960s it was preserved by Colin Shears of Winkleleigh, later being restored by a group of Welsh enthusiasts in Swansea in the livery of Gower Vanguard. It was subsequently bought by Clive Screaton for his Grand Edwardian Touring Company, which is the livery it bears in this photograph. I believe that the vehicle is now owned by Quantock Motor Services of Bishops Lydeard in Somerset.
