DESCRIPTION. This fuze is very similar in appearance and construction to the VZ (80) but differs from it in the following respects: (a) The lower part of the fuze body is not threaded to receive the special explosivefilled pocket which is fitted to the VZ (80); (b) the clock-work which controls the arming time runs for 6 or 7 minutes before the fuze arms, as against about 5 seconds for the VZ (80).

Theres is no markings on the fuze head.

OPERATION. When the bomb is launched, the arming rin of the fuze is pulled, removing the central part of the aluminum diaphragm and the spiralled arming wire. The removal of the latter releases a lever which frees the balance wheel of the clock and allows the clock to begin operating. After 6 or 7 minutes, the arm holding down the arming bolt springs to one side, and the arming detent is forced out by its spring. The fuze is now fully armed and functions in a manner identical to that of the VZ (80).
