Position and method of fixing in bomb: Screwed into the nose. Secured by a grub screw.

Components of explosive train: The entire explosive train is contained in the gaine. The primer screws into the gaine and is adjacent to the lead azide core. Two high-explosive pellets fill the gaine.

Description: The brass fuze body contains the firing pin, striker block, and spring. A lo-cating pin set in the fuze body fits into a keyway in the striker preventing it from rotat-ing. A firing pin guide screwed into the base of the fuze body. A vane hub screws down on the portion of the striker that extends above the fuze body. The locking screw in the top of the striker prevents the vane assembly from falling away. The top of the vane hub is sealed by a closing washer which is crimped over its end.

Stip studs on the vane hub and on the fuze body, prevent the vanes from binding.

A saftypin hole extends through the fuze body and striker but no safetypin has been re-covered.

There is no shear wire in this fuze.

Operation: When the bombs fall free from the container the vanes on the fuze rotate and thread out to the locking screw. On impact the striker compresses the spring and hits the primer.

Remarks: The fuze is armed after four turns of the vanes.
