DESCRIPTION

The Pistol No. 30 Mark II or III are similar in construction to pistol No. 28 Mark I except that the strikers are fitted with a sharp point. The Mark III differs from the Mark II in the method of retaining the creep spring within the body. In the Mark II Pistol the spring is held in position by a washer, the washer being retained by spinning over the end of the body. In the Mark III Pistol, the creep spring is retained by a screwed holder. An arming vane is not fitted with this Pistol, but forms part of the tail unit of the bomb, such as the A.S. 100 lb., 250 lb. and 500 lb. bombs. The Pistol is fitted with a fork running on the striker thread.

Safety Devices:– The fork is prevented from rotating during transit by a safety plate which passes through it and engages slots in the body. A press cap fitting over the end of the body prevents the entry of dirt and moisture. When completely as-sembled, the arming vanes, connected to the pistol by the arm-ing vane spindle, are prevented from rotating by the fuzing wire.

OPERATION

As the bomb leaves the plane, the fuzing wire is withdrawn from the arming vanes, and they are then free to rotate. After the fork has unscrewed, the pistol is then armed. On impact, the striker overcomes the tension of the creep spring and moves forward.

POSITION & METHOD OF FIXING IN BOMB

Screwed by hand into exploder tube adapter in base plate of bomb and secured by a spring locking collar.
