EMPLOYMENT: Small cavity fuze for 8.8-cm A.P. projectile. (See fig. 609.)

DATA:

Over-all length: 2.312 inches.

Maximum diameter: 0.812 inch.

Threaded length: 0.812 inch.

Number of threads: 14 RH.

CONSTRUCTION: This fuze contains a spring-loaded striker and is contained in a housing that fits into the base of the projectile. The detonator is fixed in the fuze. The firing pin is fitted with a spring under compression by two balls which are held stationary by a spring clip in a slight channelure just forward of the collar.

ACTION: Upon impact the collar moves forward due to inertia forcing the spring clip out of position. The balls are free to move out of position, releasing the spring-loaded striker which is forced on to the primer.

REMARKS: Another version of this fuze has been identified in which there is no spring clip or cannelure but in their place, a shear wire restrains the collar until impact.
