This book contains information about a tank very important in the development of Polish armored weaponry. Although only 38 of these combat vehicles were purchased in 1932, allowing for the formation of just two companies, it was significant that the Polish Army received a modern tank, whose utility and properties could be tested in daily service. Simultaneously, a license for the production of Vickers E tanks was purchased - and this was even more important than the acquisition of the equipment itself. Operating Vickers E tanks provided essential knowledge about the necessary design changes - which was crucial for the initiated production of more advanced Polish tanks named 7TP and C7P artillery tractors. The book includes nearly 200 illustrations, consisting of large, clear photographs from the era and colorful profiles of Polish "Vickers" with faithfully reproduced details of equipment, painting, and markings.
