Description
The grenade is composed of two parts; a bursting white phosphorus component and a generator component. Both components are made of tin plate, and construction follows normal trade practice. They are cemented together immediately after filling. The WP component is similar in construction to Grenade No. 80, but is shorter and contains about half a pound of WP. It is initiated by means of Striker Mechanism No. 3 Mk I, which fires a Detonator No. 75 Mk II. The striker mechanism is screwed into a recess in the top of the WP component above a brass detonator tube. The adapter of the striker is cemented in position. The housing can be unscrewed for priming. This housing carries the spring-loaded striker held back by the safety lever and safety pin. The adapter and housing castings are made of zinc base alloy.
The Detonator No. 75 Mk II consists of a cap mounted in a die-cast cap chamber (similar to Detonator No. 35M) with a length of Safety Fuse No. 17 Mk I Bickford to which is crimped a Detonator No. 78. The generator component is filled with HC Smoke Mixture and is ignited by a primed cambric disc, which is ignited by the flash of the detonator. This component is screwed and cemented to the bottom of the WP component.
