Each volume of the Squadron "In Action" series of books provides an in depth look at the history of a specific aircraft type. Many aspects of the aircraft's design, development, and service use are covered. Each book uses photographs extensively, and three-view drawings illustrate differences between each design variant. In addition, a colour centerfold shows the different types of markings and paint schemes of that aircraft. These books are excellent references for modelers wishing to document a scale project or as a source of ideas for colour schemes or detailing. Each book is 50 to 58 pages and measures 8 1/2" by 12".
