The Treaty of Versailles forbade Germany to manufacture tanks so the Panzer I had to be developed in strict secrecy, but by the time of the invasion of Poland the Wehrmacht had over 1400 of these light tanks. The Panzer II was an interim design, bridging the gap between the Panzer I and subsequent, far more viable armored fighting vehicles like the Panzer III and IV.
As well as tracing the history of the Panzer I and II, Robert Jackson's book is an excellent source of reference for the modeler, providing details of available kits, together with artworks showing the color schemes applied to these tanks. Each section of the book is supported by a wealth of wartime photographs as well as diagrams showing the technical changes that were made to these tanks in the course of their careers.
“This is a well-done book for a good price. There is just the right amount of detail in a book that has limited pages, and the color profiles are very well done. Enough to perhaps even inspire the next armor build! I would certainly recommend the book for all those interested in WWII German armor - especially if you have an interest in the pre-early war vehicles. For the price, I can also recommend this to the model builder with even a passing interest in the subject.” ~IPMS/USA
