B.L. 9.2-INCH HOWITZER IN FIRING POSITION
BOMBS, M.L. SMOKE 4-IN. STOKE'S TRENCH HOWITZER
MARKS IC, IMC, AND II
The diagram shows four images, the first shows the exterior body of a mark II howitzer smoke bomb, the second a cross-section of the mark II bomb, the third a cross-section of the mark IC bomb, and the fourth a cross-section of the mark IMC bomb. The diagram shows the differences between the types of bomb.
The first diagram has labels indicating that the casing of the shell was only painted dirty white and that the date of the shell's filling was written on the side. If the shell was filled with white phosphorous (rather than red phosphorous) a white band was painted on it.
The second diagram shows how a container sits inside the outer body, holding the white phosphorous for the smoke bomb.
The third diagram shows a partial cross-section of the interior of a Mark IC Bomb. Some of the central tube with the cork discs at the base can be seen, and the tubular propelling charge.
The last diagram shows a partial cross-section of a Mark IMC Bomb. Again, some of the central tube with the cork discs at the base can be seen, and the tubular propelling charge.
