Markings

This fuze has an aluminum body, which is covered at the top by a thin aluminum cap graduated from 0 to 880. Screwed into the top, the aluminum cap contains a detonator holder held off from the firing pin by a stirrup spring. This initiates the rise mechanism. The time ring is helical, having nine turns and finally leading to a gunpowder main charge in the base. The percussion mechanism consists of a detonator holder which is held off the firing pin by a brass ring, a stirrup spring, and a creep spring. To set the fuze, a hole is pierced through the cap and body against the required graduation, leaving a clear channel to the center of the fuze.

On firing, the detonator of the time mechanism stes back against its stirrup spring onto its firing pin. The flash ignites the time ring at the point of perforation. The time ring burns through to set off the main charge.

The arming ring sets back against its stirrup spring on firing. The detonator holder is now held by the creep spring. On impact, the detonator sets forward to hit the firing pin.
