Just picked up this book since it covered the bayern, konig, and kaiser classes. was ~12$ at amazon. I was unaware that the bayern carried torpedo's (that is the one thing I learned from this book).. The book has some interesting pictures, most of which I have seen before and downloaded online.. There is one slightly interesting cut away view of a kaiser class vessel. That being said, unless you have 12$ burning a hole in your pocket, you can get just about everything picture wise on these ships online for free with a little google-fu. The little morcels of good information do not suffice to make this 47 page pamphlet (I hesitate to call it a book) worth the money. Find it used if you really want it, or borrow it from the library/other boat guys. -Greg
Agreed it doesn't add much picture wise to a quick internet search. But if all you want is a brief overview of the late Imperial German dreadnoughts then it succeeds there. Like all Vanguard books don't expect much and you won't get too disappointed.
I also bought this book because I needed something cheap to get my order over the free shipping limit. I've bought a few of the naval books from this publisher and have found them all mediocre at best.
