Originally built for British South American Airways and first flown in January 1950 but not delivered and transferred to the Ministry of Civil Aviation the following month. Stored for several years at Ringway before being bought by Aviation Traders and converted, with a stretched fuselage and large rear cargo door, to a Super Trader 4B . Operated by Air Charter from 1955, mainly on Ministry of Defence contracts, before being withdrawn in 1959 and scrapped at Stansted. The fuselage survived at the fire school until 1963.

After storage in Ringway's southside Hangar 522, this was one of four Tudors bought by Freddie Laker's Air Charter company and converted to Super Trader status with large rear freight doors. G-AHNO was named "Conqueror" and is visiting Ringway on a cargo flight.
