This fuze is of the same construction, dimensions and weight as the normal A.Z. 23 fuze with optional delay (see description of A.Z. 23 v. (0.15) and Fig. 3 included in the pam-phlet) but the centrifugal segments and the expanding spring ring encircling them are de-signed to arm at a lower rotational speed. The fuze is armed by centrifugal force at rota-tionel speeds between 3,000 and 4,200 r.m.p. and the A.Z. 23 v. (0,15) between 4,500 and 5,500 r.m.p.

The fuze is identified by the designation "A.Z. 23/42" stamped above the flange. The fuze examined has been stamped to indicate a delay of 0.25 second but this had been barred out and 0.15 stamped above. It is used with the H.E. shell for the 10.5 cm Geb.H. 40 (mountain howitzer).

According to a German document the fuze can also be used instead of the A.Z. 23 v. (0.15) in every type of shell for the 10.5 cm l.F.H. 18 in which the latter is used.
