The gaine is used in conjunction with the A.Z. 39 fuze in hollow charge shell and is situ-ated in the base of the shell cavity.

The steel body is cylindrical with a flat radiussed top and a flange at the base Two rows of four flash holes are formed in the side of the body. Externally, excepting the top of the gaine, which is not extended to form a neck, it is similar in shape and size to the Mo-del 40 gaine described in Pamphlet No. 8. The overall length of the gaine is 1.025 inches and its diameter at the body and flange is 0.747 inches and 0.95 inches respectively. The circular apertute at the head of the gaine is 0.325 inches in diameter.

Internally at the top it is fitted with a suitable shaped bakelite washer above a transpa-rent wafer of viscose paper, which separates the washer and filling.

The filling consists of 78.5 grains of PETN/Wax (87/13), salmon pink in colour. The deto-nator capsule containing approximately 4.3 grains of lead azide under a thin layer of ap-proxiamately 0.23 grains of lead styphnate fits into the bottom of a cavity formed in the top of the main filling. A silk fabric disc of open weave is inserted above the detonator filling and the mouth of the capsule is closed by a flanged aluminium cup.

The base of the gaine is closed by a fibre plug having a cardboard disc on its inside and, on its outside, is a stuck-on paper disc bearing the marking "Zdlg. 40B).
