Description: Diagram of British Hand Grenade No I Mark I. Body is made of solid drawn brass, cylindrical. Around the body is a cast-iron ring which is intended to break up on detonation of the charge. Bursting charge is 4 oz 2 drams Lyddite. The weight of the cast-iron ring causes the grenade to fall nose-first, which causes the needle in the cap to be driven into the detonator, which contains 30 grains Fulminate of Mercury, and ignite the Lyddite charge. The cap is set to position "Remove", "Travel" or "Fire". Handle is of cane approximately 16 inches long. To prepare the grenade : Turn cap to right until word "remove" is opposite arrow painted on body, and remove cap. Place detonator into recess Replace cap To throw the grenade : Unwind tail and allow to hang loose Turn cap from "travel" to "fire" position Remove safety pin Grasp grooved end of cane handle and throw grenade either over or underhand, taking care not to entangle the tail. Grenade should be thrown upwards at an angle of at least 35°. This facilitates the grenade striking the ground near vertically.
