Overall length: 8 7/8 inches. |
Length of body: 5 1/2 inches (spherical). |
Diameter of body: 5 1/2 inches (spherical). |
Thickness of wall: 1/8 inch. |
Material of wall: Compressed paper. |
Type of suspension: Thrown by hand. |
Color and markings: Black over all (probably coated with a waterproofing liquid). |
Type of filling: A central burster charge consists of granular black powder in a silk bag. Surrounding the burster charge are 32 cylindrical sheet-metall pellets containing a low explosive charge. Each pellets has a 1/2 inch safety fuse which is in contact with the silk bag containing the central burster charge. |
Dimensions of pellets: |
Diameter: 1 1/8 inches. |
Height: 13/16 inch. |

Weight of filling: Burster charge: 4.50 ounces; Explosive pellets: 6.6 ounces. |
Total weight of bomb: 36.5 ounces. |
Construction of body: The missile consists of a sherical container of compressed paper from which a tubular neck of compressed cardboard projects approximately 3 inches. A wooden plug at the base of this tube houses the friction pull igniter. |
Operation: The cord of the igniter is pulled and the missile is thrown from the plane. After a short delay the black powder burster charge explodes rupturing the paper body scattering the explosive pellets and simultaneously igniting the safety fuse of the pellets. After a short delay the pellets are detonated. |
