DESCRIPTION:

This pistol is of the chemical long delay type, and has a two piece body. The upper body is a truncated cone containing a plunger hwich is spring-loaded down. This spring is compressed when the safety fork is under the plunger cap. The upper body screws onto the flanged lower body, in which is the acetone ampoule covered by a rubber disc which prevents the escape of acetone into the upper body. Beneath the acetone am-poule are celluloid discs which hold up the striker screw, which is, in turn, attached to the spring-loaded striker. The diameter of the lower part end of the pistol body is redu-ced to fit into the detonator.

OPERATION:

When the bomb is dropped the safety fork is pulled, and the plunger is forced down by its spring onto the acetone ampoule. The ampoule is broken and the acetone allow-ed to flow down onto the celluloid discs, softening them enough to allow the spring-loaded striker to pull the striker screw through thus forcing the firing pin down onto the detonator.

REMARKS:

(1) The delay is from 6 hours to 144 hours, with settings similar to the No. 37 Che-mical Long Delay pistol

(2) It must be assumed that the acetone ampoule is broken if the bomb has been dropped, even through the safety fork is still in place.

(3) No anti-withdrawal device is used with this pistol as yet.
