Type of Filling: Petroleum, 87.7%; polystyrene, 11.7%; phosphorus, 0.5%.

Fuzing: ElAZ (25) B in forward pocket. Dummy fuze head in after pocket.

CONSTRUCTION. Type I. – This bomb consists of a one-piece forging with a female-type base plate. A rubber washer fitted under this plate, but is not visible externally. (See fig. 60.)

Type II. – This bomb is of welded construction with a female-type base plate. A thick black rubber washer projects about 1/2 inch from the under edge of the plate.

The filling is contained in the bomb body in the form of a thickened liquid fuel. Supported in the filling by four metal bands fitted to a wooden frame-work are 16 brown glass bott-les in four rows, containing a very brittle form of white phosphorus.

OPERATION. On impact, the fuze fires the gaine and the picric burster pellets, breaking the case and scattering the filling over a radius of about 70 yards. The filling ignites spontaneously, burning with a great deal of smoke.

SUSPENSION. This bomb may be suspended either horizontally or vertically by an eye- bolt.

COLOR AND MARKING. The body and tail are painted blue-grey overall with a 1 inch red band located just aft of the side suspension eye-bolt. The after end, from shoulder to base plate, has only the usual red priming coat. Between the red band and the rear fuze pocket are the following words stenciled in red: "Achtung vor Sonnenstrahlung schützen". (not to be stored in the sun). Immediately below this is "Brand C 250 A" in black letters. Further markings are found between the fuze pocket and the shoulder.
