Italian armored equipment has never received the level of coverage than armored equipment from other countries has gotten. This book is part of recent efforts to correct that historical trend.
The book has 3 main sections: the walk-around of three preserved self-propelled units (two M 41 and one M 42), a section with line drawings, and a brief historical summary, with period photos.
The walk-around is clearly the most important part of the book. It covers three surviving Semoventi, the M 41 da 75/18 at Rome, the M 41 da 75/18 at La Spezia (this one is a full running Semoventi), and the M42 da 75/18 located in Rimini. The last one is in German markings and built to German specs, after the Italian surrender.
The pictures are in full color (for a total of 171 pictures among the three Semoventi), including interior pictures. They show every detail from the running gear to the weaponry, armor plates, external brackets, etc.
