CONSTRUCTION: The bomb has a concrete body of the same dimensions as the SC 10. A conical dummy fuze head of block bakelite is fitted to the nose end of the bomb. This fuze head is secured by four evenly spaced wires imbedded in cement extending through the bomb. The wires pass through four housings in the bakelite fuze head, and are secured in position at the nose by turning over the protruding ends. The other ends of the four wires are secured by passing ech wire through seperate eye holes provided at the base of the sheet metal fins and turning over the ends.
A central cavity 11 inches in length is formed within the body to accept a paper cartridge. The cartridge is seperated at the nose end from the dummy fuze head by a 1/8 inch thick felt washer.
The paper cartridge contains a glass ampoule, surrounded by a filling of chalk, the ampoule contains either chlorosulphonic acid or fuming hydrochloric acid. On impact, the glass ampoule breaks to release its contents from which smoke emits to mark the point of impact.
The four tail fins, comprising two sheets of metal which are slotted and interlocked together, are partly moulded into the concrete at the tail end and are secured by two additional lengths of wire which run laterally through the eye holes and are fastened by twisting the ends of the wire together.
COLOR AND MARKINGS: Body unpainted with 2-inch white band at nose. Tail vanes aluminum in color; nose, black. LFB 110 stenciled on body.
