The Avro 691 Lancastrian was a British and Canadian passenger and mail transport aircraft of the 1940s and 1950s developed from the Avro Lancaster heavy bomber. The Lancastrian was basically a modified Lancaster bomber without armour or armament and with the gun turrets replaced by streamlined metal fairings, including a new nose section. The initial batch was converted directly from Lancasters; later batches were new builds.
