For what it's worth, this excellent booklet was only printed in around 1,000 copies which is about the normal run for a 'specialist' military book....if you can find a copy it's well worth it...

I know the Hartenstein Museum shop don't have any copies left and it's one of those books that uses a lot of Bundesarchiv Koblenz photos and they want thier pound of flesh for using them and the cost of paying then again may put off doing a reprint.....

IMHO it's best keeping your eyes and ears open and whne someone says a book is down to low stocks and recommends it buy a copy because before you know it copies will be at silly money......look at Off at Last by Robert Sigmond, if a copy appears they are about £100...
