Taitbb,
If you haven't got shelves and shelves of books on the Luftwaffe (mostly gathering dust), you could do a lot worse than purchase this one. It contains a lot of information that is spread over numerous books, some difficult to locate (and expensive to buy). Faults, sure, show me a book that doesn't have them. It is a mine of information, and will repay its purchase price many times over.
