Ringway was opened on 8June 1937 with Menzies giving aspirited display in Battle K7563. TheAir Ministryapproached Austin Motors in February1936 about manufacturing Battle wings, and in 1938 complete aircraft. For test flying an airstrip was prepared at Northfield, almost alongside the plant at Longbridge in Birmingham. However, in winter it would not be suitable for test flying, so on their first flights the Battles were ferried to RAF Castle Bromwich wheretesting could take place. Chief test pilot for Austin was Capt Neville Stack AFC, who had asmall team including Jim Mollison to help him.
