The A13 Mk. I was the first British Cruiser tank to use the Christie suspension system and set the style for all other Cruisers built in World War II. Together with the improved Mk. II and Mk. IIA it played an important part in the battles in France in 1940 and North Africa in 1941. This book covers its development, production and service, filling a long-neglected gap in the history of British armored vehicles. It includes over 140 period black and white photos from archives and private collections, many never before published, 7pp 1/35th scale plans, 3 pp technical drawings and sketches, and 27 profusely researched full-color plates. Its author has researched British AFVs for 40 years and has contributed many articles to professional military and modeling magazines.
