The Narrow Margin says "... to enquire whether a Spitfire could be fitted with a constant speed propeller ... An extra 7,000 feet was added to the service ceiling and the machine had a better manouverability at height and improved take-off and landing perfomance ... on June 22nd, de Havilland received verbal orders to convert all R.A.F. Merlin powered fighters in the field with top priority. ... By August 15th 1,051 Spitfires and Hurricanes had been converted,"
Hope that helps.
