by Peter A. Schmidt. Hardbound, 429 pages, 9" x 11-1/2". One of the most useful references ever produced on the flintlock military muskets of the U.S. Learn the correct, and incorrect, configurations for these historical longarms. Study the markings and inspection stamps that separate rare muskets from run-of-the-mill examples. Also included is surely the most in depth explanation of the Federal System of manufacture ever to appear in print, including fascinating details about the inner workings of Springfield Armory and never before published histories of the many contractors who also made these guns.
