The authour explains clearly and precisely the chronological operational history of the P-39, describing the pilotsʼ missions during the Second World War. The text is both English and Italian and suits the aviation history lovers as well as modellers, to whom is dedicated a whole chapter about a detailed build article of the Eduard Kit in 1/48th scale. The final section deals with camouflage and markings and technical data on the type. There are a number of images, six beautiful coloured profiles and 35 epochal photographs.
