Fuzing: Type K
Color and markings: Overall reddish-brown; red nose-Magnesium: 0.084 kg
-Thermite: 0.473 kg
Fuzing: Type K
Description:
-Type I: The bomb is a tail-less cylinder made of electron metal. On the curve surface are three small holes plugged with cork. These act as vent holes when the thermite filling is ignited. The thermite is in the form of a lightly pressed filling, pressed in two halves, with a central cylindrical which is filled with magnesium powder.
Below the fuze is a powder pellet which is separated from the thermite by a paper disc which is glued to a cardboard ring. Through the paper disc is looped a piece of quick-match which extends into the magnesium.
-Type II: This type made of the same material and having the same dimensions as the Type I, differs in the internal arrangement for igniting the thermite. In place of the quick-match, a thin aluminum tube is inserted in the magnesium filling. This tube contains a number of holes on its surface covered by thin paper, and is filled with magnesium powder. It is sealed at its lower end by a cork plug.
Remarks:
1. These bombs can be dropped singly or in a bomb container.
2. These bombs were used also for sabotage work by using the fuze Type H.

The lower portion is of sheet steel and contains a high-boiling turpentine oil.
-Type II: This bomb is very similar to the Type I, except for the filling in both the upper and lower cylinders. The upper part contains magnesium and mercuric oxide powders, and the other contains nitrobenzene.

Color and markings: Overall reddish-brown; red nose
Description: The bomb consists of nose body and tail, all secured by screws. The body is electron; the nose as a steel plug; and the tail is alloy or sheet metal. Fuze vanes halfway along the tail length insure limited terminal velocity for the vanes. Five holes at the rear of the bomb casing are closed by cork plugs. The fuze functions on impact; igniter fires thermite; corks blow out and filling burns about three minutes; then casing breaks and burns with a white heat for ten minutes.
