Description: Red Type: This igniter is composed of a brass body with a red plastic outer sleeve. At one end a screw cap is fitted with an eye for attaching a pull or trip cord. Attached to the inside of this cover is a short pull string which projects through a small pellet of friction ingintion composition. The end of the igniter into which a safety fuze is crimped is covered with a piece of tinfoil to keep out moisture. The ignition pellet is con-tained in a brass tube crimped into the brass outer case.

Black Type: This igniter differs only slightly from the red igniter. The brass case is slightly longer and the black plastic sleeve slightly larger. The sleeve over the case has fourteen depressions or rings around it to give the hand a firm grip. The red igniters, the ignition pellet is contained in a brass tube crimped into the brass outer case. Tied through the eye on the cap is a heavy cotton cord to assist in pulling. The cap is not threaded but slides off.

Employment: These igniters are designed to ignite safety fuze but can be used with a detonator to ignite trip wire booby traps.

Operation: When the sanded end of the pull string is drawn through the igniter compo-sition, it ignites and flashes through the igniter body.
