with no weld marks. The suspension eye-bolt may be in the side or the nose of the bomb as in normal 50 kg. H.E. bombs.

The phosphorus-oil bomb can be distinguished from the 50 kg. H.E. bomb by the following features:—

(a) The rear of the bomb from shoulder to filling hole is painted red.

(b) The filling cap is painted red. The cap is screwed down on a clearly visible black rubber washer. (See Figure 19).

(c) A sheet metal collar may be welded to the case between the filling cap and the shoulder. The collar, which is often painted red, is drilled and tapped to take 8 screws.

(d) On one of the specimens a 1 in. red band was painted round the bomb an inch behind the suspension eye-bolt. The body of this bomb was painted dark grey-green or blue-grey.

This bomb is marked "Brand C 50 A." A later model marked "Brand C 50 B" is painted light fawn colour and has two red bands ¾ in. wide, one on the nose and the other between the tail and suspension lug (see Figure 18). In this type the case is of welded construction and the base filling cap is the female pattern with two studs projecting rearwards.

There is also a larger version of this bomb in a casing similar to a 250 kg. H.E. bomb. The filling is similar to that of the 50kg. type, but the rubber content has been increased to 13% and that of the phosphorus reduced to 0.4%.

The phosphorus content of these bombs may be carried in glass containers designed to break on impact and mix with the main filling. Bombs so filled have a representation of a glass container 40 × 80 mm. stencilled in red and "Brand C 50 A "; "Brand C 50 B"; or " Brand
