This is the second and final volume of a highly detailed and extraordinarily well researched piece of work, which has never been attempted in such a way before. It is effectively unique and will become a standard reference for enthusiasts, aviation historians and authors. The book will be profusely illustrated with a large number of unseen photographs depicting bomber aircraft in their unit markings with, wherever possible, close-ups of the unit emblems and badges, of which many could be in colour. In addition the book contains unique photographs of many of the unit commanders.
