Avro 652A Anson C.19 VL348/G-AVVO
Photographed at Newark Air Museum on 10 May 2005.
The Avro Anson had one of the longest productions of any British aircraft, with an unbroken run from 1934 to 1952.
It began with an Imperial Airways specification sent to AV Roe in 1933 which requested a four-passenger aircraft capable of flying 420 miles at 130mph.
In August 1933, designer Roy Chadwick completed plans for the Type 652, a low-wing monoplane with retractable landing gear to be powered by two Armstrong Siddely Cheetah V engines.
Imperial ordered two in April 1934 and the first flew on January 7, 1935. The type's order potential received a boost in May 1934 when the Air Ministry notified AV Roe of a requirement for a new coastal reconnaissance type and the company came up with the 652A.
The Air Ministry then gave the company less than six months to build the first prototype, which had not yet flown in its civil guise. But AV Roe completed the job and flew its first 652A on March 24, 1935. It differed from the civil version by having rectangular rather than rounded windows and featured a dorsal turret with a Lewis machinegun.
The type won the selection competition and the RAF ordered the Anson GR Mk.I, the first flying on December 31, 1935.
With the end of the war in sight, Avro developed the Avro Nineteen for intended airline use and 264 were built, mainly for the RAF as the C.19. The type was retired from RAF service in June 1968.
