To my mind, the short list of the last real vestige of the rampart-style gun were the metallic cartridge Rummer wall-gun of 1874; a later huge, two-man, 6 1/2-foot-long bolt-action Chinese Jingal cartridge; the massive 41-pound, 13.5mm Mauser-style German Tankgewehr Model 1918 of World War I; and the World War II British .55 Boys Anti-tank Rifle--the latter two's roles adjusted for changing conditions in warfare.
