Description: The sling grenade consists of a steel grenade body, wooden base plug, reinforcing cloth, scratch type friction ignited fuze, wooden fuze seat, wooden spacing ring and a metal protective cap.

The rough, cast steel cylindrical grenade body has a hollow projection on its forward end into which the wooden fuze seat and fuze are fitted and secured with glue. The after end of the body opens directly into the TNT filled explosive cavity of the grenade. This opening is closed by the wooden base plug, which is glued in place. The throwing line is attached to the after end of the wooden base plug.

A strip is reinforced cloth is wrapped around the base plug and the after end of the gre-nade body in order to help prevent the two sections from pulling apart when a line is used to throw the grenade. The cloth is lashed securely in place by light line, which is tied around the annular groove in the grenade body and the cylindrical after section of the base plug.

A light, sheet metal cap is sealed over the nose of the grenade with water-proof paper tape. The wooden spacing ring prevents contact between the fuze and the protective cap. A flat surface on the side of the ring is coated with the abrasive compound used to ignite the fuze.

The fuze for the sling grenade is made in two sections: a long brass detonator tube and a short igniter head. This tube is pierced by a single gas port and is crimped to the deto-nator tube.

Operation: The abrasive on the spacing ring is rubbed against the match head of the fuze to ignite the match composition which initiates the firing train. The grenade is then thrown by hand or by means of the line attached to the ring in its base. The delay is from 4 to 5 seconds.
