EMPLOYMENT: Nose fuze used on German 20-mm ammunition. (See fig. 552.)

Over-all length: 1.000 inch.

Maximum diameter: 0.781 inch.

Threaded length: 0.250 inch (with washer).

Number of threads: 6 RH.

CONSTRUCTION: The fuze is aluminum and has a recess in the base with houses a deto-nator cup. A floating striker is held in position by a coiled aluminum tape bearing against a shoulder on the striker body. A wooden hammer rests against the striker head and is just below the nose closing cap.

ACTION: Centrifugal force unwraps the aluminum tape freeing the striker. On impact, the hammer forces the striker into the detonator.

REMARKS: The A.Z. 1502, an earlier version of the 1502 F, employs the standard German centrifugal segments surrounded by a coiled strip of brass, but that is the only difference in the two fuzes.
