Avro 691 Lancastrian

The first conversions of the Lancaster bomber to the high-speed long-range transport Lancastrian, were made by Victory Aircraft Ltd in Canada. Trans-Canada Air Lines operated these conversions on behalf of the Canadian government on transatlantic mail and passenger services between Montreal and Prestwick. The Canadian Lancastrians were fitted with Packard-built Rolls-Royce Merlin engines and accommodated ten passengers.

Production of the Lancastrian was later undertaken by Avro and deliveries were made to the RAF, BOAC and British South American Airways Corporation.
