A.V. Roe and Company, one of the great British Aircraft Manufacturing
firms, was founded in 1910 by the famous aviation pioneer Alliott
Verdon Roe. Over the next fifty-three years the company produced a
multitude of machines from its factories in Manchester and
Southampton, including such types as the 504 trainer, the Lancaster
bomber and the impressive delta-wing Vulcan.
A.V. Roe left the company in 1928 when it was taken over by Armstrong
Siddeley, the fore-runner of Hawker Siddeley. The name Avro, dropped
in 1963, was recently revived by Hawker Siddeley's successor, British
Aerospace, when they formed a new subsidiary, Avro International
Aerospace.
