A drawing of the empty shell and details of the method of filling with T.N.T. are given in Pamphlet No. 1, pages 18 and 19. The amatol burs-ting charge is of the 40/60 variety and is filled by the direct casting method through the base. The weight of the filling is 1.9 lb. The walls of the cavity and the inner surface of the base plug are coated thinly with a bituminous composition. A steel exploder container for the gaine is screwed into the nose of the shell below the fuze-hole. The exterior of the container is also coated with bituminous composition.

Details of the gaine C/98 are given in the section on German gaines in this pamphlet.

The graze and direct-action fuze A.Z. 23/28 with optional delay is similar in construction and action to the A.Z. 23 Rh.S. (0.25) described in Pamphlet No. 1, page 7. The alumini-um delay holder is stamped 0.2 on its upper surface, and it is possible that this indicates a delay of 0.2 second.
