This site, Spitfire pilots and aircraft database if I read it correctly, is used in conjunction, with permission, with this site... Spitfire - Main This site, though not in any sort of order as the latter site has 1530 pages of serial numbers and photos, when available of said aircraft. A big plus is that it also gives the names of pilots, and when available, aircraft they flew and history. You can also look up aircraft by serial number, model, factory or engine. Pilots are also searchable. Definitely worth bookmarking.
De Havilland Production lists. The production lists do not include the First World War designs of Geoffrey De Havilland and built by the Aircraft Manufacturing Co (Airco)
