1394-281

Description

This fuze is a combination long delay, anti disturbance tail fuze, and consists of a No. 881 fuze mechanism placed in a No. 28 pistol body. There is a deep V-slot cut through the base of the upper body, which is covered with adhesive tape. The detonator in this fuze is not shuttered.

The detonator in this fuze is not shuttered, but is at all times aligned with the striker. An internal weakening groove is cut around the inside of the head of the fuze, completely severing the fuze head except at four equi spaced places, which are 0.2 in. wide. Alternatively, instead of the internal weakening groove, a deep V-groove may be cut around the outside of the fuze. The external open portions of the groove are covered with adhesive tape. The weakening groove ensures that the fuze head will shear at the weakened point rather than at another point where fuze functioning might be obstructed. It also increases the difficulty of identification by means of external fuze characteristics, and eliminates surfaces to which a wrench might be applied for extraction purposes
