Editing Avro (section)

===Interwar years===
After the boom in orders during the First World War, the lack of new work in peacetime caused severe financial problems and in August 1920, 68.5% of the company's shares were acquired by nearby [[Crossley Motors]] which had an urgent need for more factory space for automotive vehicle body building.<ref name=Crossley>Eyre, M., Chris Heaps and Alan Townsin.

In 1924, the company left [[Alexandra Park Aerodrome]] in south Manchester where test flying had taken place since 1918; the site was used for a mixture of recreation and housing development. A rural site to the south of the city was found at New Hall Farm, [[Woodford Aerodrome|Woodford]] in Cheshire, which continued to be used by aviation company [[BAE Systems]] until March 2011; the site has now been earmarked for a mixed use development. 

In 1928 Crossley Motors sold AVRO to [[Armstrong Siddeley]] Holdings Ltd.<ref name="Crossley" />  In 1928 A.V. Roe resigned from the company he had founded and formed the [[Saunders-Roe]] company, which after World War II developed several radical designs for combat jets, and, eventually, a range of powerful [[hovercraft]]. 

In 1935 Avro became a subsidiary of [[Hawker Siddeley]].
