Shown here in April 1940 is Spitfire Mk.IA, (P9450) showing the production standard and markings of the period. Most noticeable features are the tapered aerial mast (replacing the earlier 'stick' type) and the addition of an external armoured windscreen. This aircraft went to No.64 Sqd based at Kenley, was damaged during the Battle of Britain, and was afterwards converted to a Mark VA.
