British Bomb, 40 lb GP Parachute, Mk 1, Mk 2, Mk 3
This bomb has a cast-steel body, the nose end of which is fitted with an exploder container screwed and cemented in position, and locked by a locking screw. The exploder container is threaded to take the pistol. The rear end of bomb body is closed and reduced in diameter to form a spigot with a central boss, which is drilled and tapped to receive an eyebolt. The parachute tail unit is secured to the body by means of the eyebolt.
The parachute tail unit consists of a cylindrical strut attached to the rear end of a tail tube by four fins. The parachute is packed in a fabric cylinder, which is closed at its rear end and fits inside the tail tube. The rear end of the fabric cylinder is connected by pilot lanyards to a flanged cover which fits loosely in the cylindrical strut and is retained in position to close the rear end of the tube by means of a wire transit clip.
This bomb is usually used as fragmentation bomb, and is identical to the 20-lb. parachute fragmentation bomb except for size.
