Japanese Bomb, Chemical, Land, Type 1 No. 6 Mk 1
The chemical fillings for these bombs are contained in cans which fit inside the bomb casing, and are sealed in place with paraffin. Two cans were used for each bomb; a conical can which fits into the tail cone, and a cylindrical can with a channel down its center to provide space for the central explosive burster charge. Besides the central burster charge, a nose charge is provided, separated from the forward end of the gas containers by a spacer disk. The nose charge is designed to have the effect of forcing the spacer disk and chemical filling back out of the crater, and help to spread it.
Nothing else to see.
