These grenade consist of a thin iron or steel casing, or head, containing the explosive filler, which is screwed onto a hollow wooden handle. through the center of which runs a double length of cord. This cord is attached at one end to a lead ball which is part of the igniter, and at the other end to a porcelain ball. The cavity in which the porcelain ball rests is closed by a metal cap that screw on. Inside the cap is a spring-actuated metal disc that prevents movement of the porcelain ball. (See fig. 284.)

These grenades use igniters B.Z. 24 consisting of a lead tube or sheath connected to a threaded brass fitting by a short steel tube. The steel tube is threaded on both ends and contains the powder delay pellet. The lead tube contains the copper capsule which holds the friction composition. The friction wire is cast in the friction composition and contain-ed in the capsule which is coiled at the bottom to provide resistance to pulling and joined to the "pull" loop at its opposite end. When the loop is pulled, it frees itself from the lead tube drawing the wire through the friction composition and the resulting and the resulting flame ignites the delay pellet.

OPERATION. The metal cap is unscrewed from the handle and the porcelain ball is pul-led. This will pull a wire through the delay pellet. The grenade is the thrown and after a 4- to 5-second delay the delay pellet will initiate the detonator.
