This is one freaking AWESOME book. It's only on the IX and the XVI (sisters if you will) with pretty much full color photos of the whole aircraft. Broken down like most detail books in to fuselage, wings, gear etc… but some of the most vibrant colorful photographs in large detail pictures I've ever seen in a book of this type. Each wing (C, E, regular tip, clipped tip etc…).
I've heard good things about this series of books, I didn't understand until I got this one! In my opinion IT'S A BUY!
