The Yellow Series from Mushroom Model Publications covers individual aircraft in great detail. This book on the Boulton Paul Defiant is an excellent example. The book starts out with the basic concept of the Defiant as a daytime bomber destroyer. It then covers night fighter operations, followed by air-sea rescue operations, its use as a target tug and other tasks.
Along with, and in addition to the description of the operational history of the Defiant, a great number of photos are included. These show experimental and operational aircraft as well as incredible details of all parts of the aircraft. The majority of the detail photos were taken of the only complete surviving example of the Defiant at the RAF Museum Hendon. The modeler will be very pleased with these detailed color photos.
