The light-case, hemispherical-based shell, fitted with the direct action fuze No. 1502 is the same as that used in the Oerlikon type. The shell and fuze are described in Pamphlet No. 3.

This is the light-case, hermispherical-based shell as used in the Oerlikon type (described in Pamphlet No. 3), but the self-destroying fuze Z.Z. 1505 is used instead of the A.Z. 1502. A drawing and description of the Z.Z. 1505 are included in this pamphlet.

This is the light-case, hemispherical-based shell as used in the Oerlikon type (described in Pamphlet No. 3), but has a cast filling consisting of an H.E. intermixed with a metallic substance.

Cartridges of this type have been found with the delay magazine in the Z.Z. 1505 fuze and an electric primer instead of a percussion cap in the case.

Drawings and description of the delay-magazine of Z.Z. 1505 and the electric primer are included in this pamphlet.

Cartridges of this nature have been found with percussion caps and N.C. tubular propel-lant or with electric primers and N.C. flake propellant.

This projectile with its inert filling is the same as that used in the Oerlikon type and is shown in Fig. 22.

The shell body is the same as that of the A.P. shot shown in Fig. 22, but the cavity con-tains a filling of P.E.T.N./Wax. A gaine is fitted in a cavity formed in the base of the filling and the base of the shell is closed by an igniferous base fuze. A cavity formed in the fuze body contains an aluminium cylinder fitted with a small initiator pellet of the ignifer-ous type at the front end and open at the base end. A needle, with two splayed project-ing pieces, is positioned at the open base end and is prevented from approaching the pellet by two projecting pieces bearing against the wall of the cylinder. The fuze is clo-sed at the front end by a screwed plug with a small central hole. The gaine consists of an aluminium flanged cup inserted in the cavity in the bursting charge with its open end towards to base. The cup contains a filling of the intermediary class which is topped near the open end by an initiator composition. An empty space is left at the open end of the gaine.

On impact the needle overcomes the projecting pieces and, moving forward, pierces the igniferous pellet. The flash produced passes through the small hole and initiates the gaine thus bringing about the detonation of the bursting charge.

FILLED H.E.

The shell body is the same as that of the A.P. shot shown in Fig. 22 but, instead of an inert filling, the cavity contains a light alloy container charged with phosphorus.
