Width of fuze body

The fuze has four large arming vanes attached by two set screws to the threaded por-tion of the withdrawal rod. The cylindrical body is threaded beneath the shoulder to screw into the base of the bomb. The striker and detonator resemble Types E, F, P and W, which incorporate the "all-ways" feature with the creep spring. The fuze is internally threaded at the base to receive the long Italian booster.

The safety pin is removed when the fuze is screwed into the base plate. A spring-loaded stop protrudes from the base plate to prevent rotation of the vanes. After the aerial burst nose-fuze function, the small bombs are released from the container, and the spring-loaded stop goes forward, freeing the vanes to rotate. The rotating vanes rise above the fuze head, withdrawing the arming spindle, which releases the steel balls. These, in turn, release the striker. Upon impact, the detonator holder and striker are brought together, regardless of the position in which the bomb lands.
