This is an original 1941 dated Instruction Manual for the Semi-Automatic Johnson Rifle as used by the United States Marine Corps in the early part of World War 2. Manual is a bit worn but remains in decent condition with no significant damage and no pages appear to be missing. Back cover has a fold-out schematic of the Johnson rifle. Rarely seen. This would be a great addition to any Johnson, WW2, or USMC Collection.
