Body Construction: |
|
No. 14 Mks I and II, and No. 18 Mks I and II – The body, tail plates and burster con-tainers of these bombs are the same as those of the No. 1 Mks I and II. In addition, the No. 14 Mk I has a nose weight of cast iron. The Bombs No. 14 and No. 18 have no cen-tral flash tube, but use double-length candles, whose primed ends rest against a primed cambric disc on the perforated ejector plate. Steel tubes may be substituted for wooden battens. |
|
No. 14 Mks III and IC, and No. 18 Mks III and IC – The body, tail plate, burster con-tainer, central flash tube, and tail-fuze adapter of these bombs are identical to those on the corrosponding marks of the T.I. Bombs No. 1. The Nos. 14 and 18 have an unperfor-ated central tube and no division disc, as double-length candles are used. The candle's primed ends rest against a primed cambric disc on the perforated ejector plate. |
|
Functioning: No. 14 Mks I and II, and No. 18 Mks I and II – Functioning of the fuze ignites the burster charge, which flashes through the perforated ejector plate to ignite the cambric and candles, and ejects the candle after forcing off the base plate. |
|
No. 14 Mks III and IC, and No. 18 Mks III and IC – If nose-fuzed, these bombs func-tion the same as the Mks I and II, except that the central tube instead of battens forecs off the tail plate. If tail-fuzed, the flash of the fuze is carried by the primed cambric tube to the nose burster charge, after which the operation is the same. |
|
Tail Construction: Same as for the T.I. Bomb Tails No. 1. |
|
Suspension: The bomb is suspended by a single lug, which is welded to the body. |
|
Filling: No. 14, 24 type G candles; No. 18, 24 Type H candles. |
