The Mark XVI Spitfire was a late variant powered by the Packard Merlin engine which appeared towards the end of World War Two. The book tells the story of Spitfire XVIs used by Polish pilots in Britain, covering the years 1944-1946, both in Polish squadrons and in RAF and auxiliary units. It includes listings of losses and of officially credited victories. There are over 200 photographs (about half of which have never been published before) and about 30 specially commissioned colour profiles (plus top and bottom views for two representative aircraft).
