DESCRIPTION. Igniter consists of a cylindrical brass body containing a spring loaded striker held in position by a friction fit of the Z type with a cap to which is attached a large steel ring. The percussion cap holder is threaded outside throughout the entire length, thus allowings it to be screwed into the igniter in either a safe (percussion cap away from the striker) or armed (percussion cap toward the striker) position. (See fig. 254.)

OPERATION. A strong pull on the steel ring detaches the striker release plate from the striker, permitting the striker spring to drive the striker into the percussion cap.
