(Fig. 4)

This fuze is of the same construction, dimensions and weight as the normal A.Z. 23 fuze with optional dealy (see description of A.Z. 23 v. (0.15) and Fig. 3 included in this pam-phlet) but is fitted with a stronger spring between the graze and needle pellets instead of the normal spring. The load required to bring the mechanism into the fired position is between 99 and 106 ounces as compared with a load of 16 to 19 ounces for the normal A.Z. 23.

The fuze is identified by the designation "A.Z. 23/28" stamped above the flange where the time of the optional delay, 0.1 second, is also stamped.

The fuze is used in H.E. shell for the 8.8 cm Flak 18, 36 and 41 (8.8 cm multipurpose guns), also for the 8.8 cm Pak 43 (anti-tank gun).
