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 a stated first edition in good shape: the hardcover's jacket has some edgewear and nicks, a scuff on the front, but pages are clean and snug; book sits straight. A great reading copy of an undersung entry in the subgenre.
