By far the most comprehensive and detailed selection of images I have come across for the subject matter.
The historic nature of the subject of LMS wagons means the book (a reprint) cannot be considered out of date at all.
Whilst the book title suggests an "illustrated history", the captions to the excellent selection of images tend to be descriptive, referring more to differences in build details on the wagons themselves rather than a history of their lives.
However as a modellers and historians aid, it is unrivalled and therefore to be highly recommended. Many wagons included in the book are almost non existent in other literature so much can be gained in terms of both written information and rare images.
