More of a historical record - with reprints of armour related period text, invoices, and treaties. A few photos of armour and period engravings. An interesting read for the armour historian - not a 'how to' or 'techniques' text.
I don't mind the fact that this book is a little dated. I enjoyed the descriptions and illustrations and learned a few things that I hadn't known already. Although ffoulkes is a little biased about the types of armour he prefers, he none the less presents information and construction elements that apply to all harnesses. There are references in french that aren't translated, and several erroneous footnotes that are untraceable and confusing. Besides it's downfalls, there are excellent points to the book: easy to read, easy to follow, and full of tidbits you'll be pleased to rediscover when you pick it up for a second or third time. It is definately worth the inexpensive price, and should be on the reference shelf of armour enthusiasts.
