Description: This pistol is of the chemical long-delay type used in the side pocket of the above-metioned bombs. Extending out of the brass body is a steel arming screw. At the top of the arming screw is fastened a brass or steel pulley, around which is wrapped a phosphor-bronze wire. This wire is secured to the pulley, runs out through a guide key, and is soldered to the safety clip, which is located between the pulley and the head of the pistol. The safety pin passes through the arms of the safety clip, preventing the lat-ter from being removed accidentally. Below the arming screw is an ampoule of acetone, which is scaled in by a rubber washer above it. Below the acetone ampoule is a zinc sea-ting disc, which acts as a knife edge to breake the ampoule, and a celluloide disc, which holds up the spring loaded striker and its retainung balls.

Operation: When the bomb is put in the plane, the safety pin is removed. Upon re-lease, the safety clip is pulled out, and the wire, which is attached to it and also around the pulley, is reeled off the pulley. This screws the arming screw down into the acetone ampoule, breaking it and allowing the acetone to run out onto the celluloid disc. When the celluloid has become softened the force of the compressed firing spring cams the re-lease balls out, and forces the striker against the detonator.

Remarks: This pistol has a ½-hour delay, and has no anti-withdrawal device incor-porated in it.
