These are free fall, fin stabilized, photoflash bombs designed to air burst at advantageous heights to provide illumination for nighttime aerial photography. A box-fin, permanently attached to the bomb body, and a filler hole closed by a cover plate, are located in the tapered end of the after body. The magnesium-aluminum composition in the M122 contains no oxidizer and depends upon atmospheric oxygen. Therefore, it is relatively insensitive compared to photoflash powder.
The bombs may be painted gray with black markings, olive drab with white markings and a white band, or white with black markings.
No information about hazardous components.
Nothing else to see.
