Good Day All,
No need to introduce this series anymore and one more title is available covering the operational debut of the Spitfire Mk I with the Auxiliary squadrons (602, 603, 609, 610, 611 and 616) between September 1939 and June 1940. The book is made of over 50 pages, +40 photos and eight colour plates.
