A technical illustration of a firearm, specifically a matchlock musket. The main diagram shows a long, straight barrel with a spear-like bayonet or decorative tip at the bottom. To the left is a separate detail drawing of the curved wooden stock (Qiangbing). Labels indicate specific components of the weapon.
The length is four feet and eight inches, and it weighs eight catties. The rear is fashioned with a spear tip, nine inches long, with a straight handle of nine inches and three tenths, which serves as the scabbard. The slanted handle is one foot and one inch.
