Description: The igniter body is made in two sections. The forward section, which con-tains the primer cap and a black powder relay, threads into the after section and is sta-ked in place.

The after section houses the firing assembly whose components are a two-piece striker, striker spring, safetypin, and lanyard. The juncture of the two striker sections is effected by a notched joint. The striker spring bears against the igniter body and the striker flan-ge. The safety pin is inserted through holes in the igniter body and the after section of the striker to which the lanyard is attached.

Employment: Not known. Could be used as a pull firing device for booby traps.

Operation: Before firing, remove the safety pin. A pull on the lanyard draws the striker to the rear compressing the striker spring. When the notched joint of the striker is drawn past the end of the igniter body, the forward section of the striker is disengaged and dri-ven forward by the compressed striker spring. The striker impings upon the primer cap which ignites the black powder relay.

To render safe: Insert safety pin and cut trip wire if present.
