Black overall.
The container is formed by three interlocking lengths of corrugated sheet steel. Each end is closed by a hollow cone made of sheet steel. The three interlocking lengths are held in position by two sheet steel bands and buckles. The buckles are prevented from opening by two arming wires.
Attached to the tail piece are three manila cords 13 inches long. To each of these is attached a steel hook which fits into a hole in each of the three body sections.
One of the three interlocking corrugated lengths serves as the top of the bomb. Spot welded to this is a smooth semicircular sheet steel piece 25 1/2 inches long. The Army type suspension lug is attached to this piece. Eyebolts are welded on either side of the lug to serve as guides for the arming wires.
Payload is 30 Type 2 40mm 1/3 kg bombs.
Fitted around the container there may be a safety device consisting of a canvas strap, a black powder burster charge in a small container, and a friction igniter with a 2-second delay. The igniter cord is attached to the arming wire and as the container leaves the plane the delay train is ignited. After 2 seconds, the strap is blown apart and the sections of the container fall free.
