This should be considered a reference work for naval buffs. It contains a comprehensive set of detailed drawings of the construction of a Flower class corvette as used principally during the Battle of the Atlantic in World War 2. There are only 12 pages of text (including Acknowledgments and Introduction), 13 pages of photographs and the rest, 125 pages, of detailed drawings. The dust cover is itself a large drawing! It is a valuable work for model buffs whether for scratch building or modifying an existing model kit (i.e. the Revell plastic model kit, which I have, and will be converting to radio control).
The reader is expected to have extensive naval knowledge already - unfortunately, no glossary is provided for those of us who are less well informed.
