DESCRIPTION:

The pistol is made entirely of mazak, a zinc base alloy, and has a body, striker, and vane cap. The upper pistol body has four slots for locating the safety pin, which passes through the vane cap and rests in front of one of the parts of the pistol body, thus preventing the rotation of the vanes. The lower end of the pistol body is of reduced diameter and fits into the detonator. Around the body are twelve depressions which hold the tab locking device. The striker and pressure plate are cast in one piece with a threaded hole in the top of the striker to receive the vane cap screw. On the top of the pressure plate there is also a stop pin to prevent the vane cap from being screwed down too tightly. Trough the striker and the pistol bodie is an aluminum shear wire. The van cap has four vanes integrally cast with it, and it is riveted to the vane screw. In the side of the vane cap is a small hole to accommodate the safety pin.

OPERATION:

When the bomb is put in the plane the safety pin is removed, and upon release the vanes are freed to rotate. The vane screw threads out of the pressure plate and the vane cap and vanes fall away leaving the striker and pressure plate exposed. (Spring loaded wedges fly out - Mk IM to IV). On impact the shear wire is sheared and the blunt firing pin hits the detonator.

REMARKS:

(1) The Mk IM is like the Mk I except that there is a pair of spring loaded mazak wedges fitted into opposite slots under the pressure plate to prevent the pistol from firing when dropped safe on a hard target.

(2) The Mk II is the same as the Mk I except that the body, striker, and vane cap are of brass rather than of mazak.

(3) The Mk IIM is similar to the Mk KK but with two spring-loaded brass wedges un-der the pressure plate.

(4) The Mk III is like the Mk IM except that the shear wire is of brass.

(5) The Mk IV is the same as the Mk IIM, but with a brass shear wire.
