By Bonar Menninger. I've tagged this "crackpottery," because for several dozen pages, it's going to feel like that -- a crap-ton of information about ballistics texts and firing pins that might seem like it's going the usual nowhere. It isn't, and if you can stick with the dry table-setting, the book will change your whole conception of the JFK assassination.
...maybe I need to tag myself as a crackpot. Anyway, this is the older paperback edition, which is somewhat rarer, and it's not in great shape -- a multiply-cracked spine, which leans somewhat; edgewear to the covers, and a sticker ghost on the front -- but the pages are clean, tight, and not too toned. A great reading copy of an undersung entry in the subgenre.
