Every pile of dusty old books you find at a gun show has a zillion reprints of Cartridges of the World and how-to pamphlets on stock refinishing from 1960. But occasionally you'll find a real gem in those piles - and this book is one of the gems. Written by R.K. Wilson and published in 1943, the Textbook of Automatic Pistols gives a deeply technical explanation of all the very early automatic pistol designs, including a bunch of very unusual ones virtually never seen these days. It also covers the design and ballistics of the cartridges used by these guns - cartridges like the .45 Mars, .35 S&W (yeah, the .35), and 5mm Clement. It's an absolute wealth of information that you can't find anywhere else. If you would like a copy, you have three options. One is to keep a lookout for one at gun shows - you may find it sooner or later. Two is to go online and find a copy of the original printing and pay $100 or so. Three is to go to Amazon and get a copy of the 1990 leather-bound reprint by Wolfe Publishing for a paltry 25 or 30 bucks (see link below). You'll have to go through a 3rd party dealer to find it (Amazon doesn't stock it themselves), but for that price I think it's a screaming deal and worth the extra effort. http://www.amazon.com/gp/product/B0013K8T2M/ref=as_li_tf_tl?ie=UTF8&tag=forgoweapo-20&linkCode=as2&camp=1789&creative=9325&creativeASIN=B0013K8T2M
