The bomb body consists of a pot-shaped, cast-steel cylinder which is open at the top. A steel neck ring, having internal threads to receive the adapter, is welded to the open end of the body. The parachute tray is secured to the adapter. Extending through the adapter is the fuze, which is enclosed by a paper tube 2-in. in diameter, extending through the bomb body.
The parachute is 12 in. in diameter and is encased in a cylindrical steel tray having a diameter slightly less than the maximum diameter of the bomb body. A safety pin extends through the parachute container, and is secured by a spring clip.
The Mk 1 Bomb had a smaller filling hole than the Mk 2. The Mk 1 was never filled or adopted for service use.
No information about functioning.
