Detail & Scale’s original volume on the B-24 Liberator and its variants was published in 2000. Since the first volume was published, more information regarding the B-24 and its variants has become available and more photographs of the B-24 in service have surfaced. In addition, the authors were granted access to the interiors of the B-24D preserved at the National Museum of the U.S. Air Force and the PB4Y-2 Privateer preserved at the National Museum of Naval Aviation, to take reference photographs.
The book is primarily a visual reference book, so there is just a brief overview of the B-24 and its many users around the word. The history section includes a nice table explaining the two letter suffixes used to designate where a particular aircraft was built. As explained later in the book, the suffixes can be very useful in narrowing down some of the details of a particular aircraft due production differences between the various manufacturers/plants.
