CONSTRUCTION. Container is similar in appearance and dimensions to ABB 500 container with the exception that loading hatch is absent as in the AB 500-1. (See fig. 111.)

A 7/16-inch internal diameter steel tube, welded to the upper half of the casing directly above the longitudinal joint of the two halves of the container, connects at right angles to the side of the fuze pocket to which it is also welded.

A single length of green detonating fuze leads from this tube to turn along the longitudi-nal joint and run round the nose of the container, returning via the junction of the tail to enter the 7/16-inch tube. At intervals along the longitudinal joint steel clips are placed to secure the detonating fuze firmly in position.

The two halves are hermetically sealed together by welding at the longitudinal seam. In-side the container is a steel strut, which is used to give support to the two halves of the casing. The strut is weakened in one place.

Screwed to the fuze in the normal way is a standard gaine projecting into a wood pack-ing piece. One end of the detonating fuze is housed in this packing piece to contact the side of the gaine.

On release of the container, fuze is charged. After a short delay, fuze fires, firing gaine which in turn detonates the detonating fuze. Detonating wave travels round the seam of the container to separate the two halves. The weak part of the internal supporting strut is broken and the two halves are parted.

REMARKS. The Streubrand C 500 appears to have been an inefficient incendiary wea-pon, and the method of separating the two halves of the container may have been found to be unsatisfactory in practice since damage to exposed detonating fuze would result in failure.
