Because the Winchester Model 1897 and 1912 were the most commonly used combat shotguns up to the Vietnam War period, the book concentrates heavily on these two models, but by no means neglects the many Remington, Stevens, Ithaca, Mossberg and other shotguns used by U.S. military forces to the present day.
A part-by-part analysis of the Winchester Models 1897 and 1912 is provided with emphasis differentiating between World War I and World War II models. Serial number ranges are listed and factory and inspector's markings are interpreted. The differences between riot guns and trench guns are explained and the different variations of bayonet mount/handguards are described and related to serial number ranges. The many and difficult problems in determining if a particular riot or trench shotgun was used by the military during World War I is explained.
During World War II, the U.S. military purchased variety of shotguns from several different companies. Some of these shotguns were originally built and marked for the civilian market. Each variation is explained and points of identification are listed. Shotguns purchased and used by the U.S. military through the Persian Gulf War are included.
