British Bomb, 1900 lb GP, Mk 1, Mk 2




Mk 1 - The body consists of a hollow steel casting open at each end, with the nose end threaded internally to house a nose bush, which is screwed and cemented in position. The bush is bored centrally and threaded for part of its length to take an exploder container. The exploder' container is locked to the nose bush by a locking screw, and is threaded internally at the open end to house a detonator holder, which takes a pistol or transit plug. The after end of the bomb body is shaped externally to take the tail, and provided with a locating pin to locate the tail when in position on the bomb. A male base plate screws into the base of the body and is cemented in position. It is bored and threaded internally to receive an exploder container, which houses a detonator holder in the same manner as that at the nose. A flat seating at the center of gravity is drilled and tapped to take four screws which secure a suspension lug.

Mk 2 - Similar to Mk 1, except that the spigot on the tail end of the body for locating the transit base, and the seating on the bomb body for the suspension lug, are omitted.

The bomb uses single suspension in the form of a stop plate with an integral lug. The plate has four holes for the securing screws in attaching to the bomb body.

The Anti-Disturbance Fuze No. 845, formerly incorporated in the nose when the Tail Pistol No. 37 was used, is now obsolete.

The tail fins are usually painted red when a time pistol is used.
