The shell is used in the 10.5 cm medium gun "s. 10 cm K.18" with the mechanical time and percussion fuze "Dopp.Z. S/60s" (described in Pamphlet No. 10) or with the combined D.A. and graze fuzes, with optional delay, "A.Z. 23 v. (0,25)" or "A.Z. 23 v. (0,15)". The fuze with 0.25 second delay is described in Pamphlet No. 1. A description of the fuze with 0.15 second delay is included in this pamphlet. The shell is also used in the long 10.5 cm turret gun "lg. 10 cm K.T." with the "Dopp.Z. S/60s" fuze.

The body of the shell is painted the normal deep olive green, is stencilled in black and has two driving bands. The stencilling includes the H.E. numeral near the nose ("13" indi-cating amatol 40/60 and "14" cast T.N.T.), the weight class in Roman numerals at the shoulder and the smoke box marking below the shoulder (R.11 indicates the inclusion of smoke box No. 11). The smoke box marking is omitted in some instances although this component is present.

The fuzed shell is 19.1 inches in length and weighs 33 lb. 9 oz. 8 dr. when filled and fu-zed. Each of the fuzes used has a protrusion of approximately 3.7 inches.

The shell is in two parts, the head being screwed into the body about half way up the ogive. The body is of forged steel and is fitted with two copper clad driving bands of iron. The cavity in the upper part of the body is cylindrical. In the lower part it tapers towards the base and is machined. The head is a machined forging and is screwthreaded internally at the nose for the insertion of an adapter fitted with an exploder container and for the fuze. The exploder container is of mild steel. The weight of the empty shell is 26 lb. 2 oz. 6 drs. The diameter at the shoulder is 4.11 inches (10.44 cm).

The bursting charge consists of cast T.N.T. or amatol 40/60 with a cavity below the fuze hole which contains a No. 11 smoke box beneath the exploder container. The weight of the amatol 40/60 bursting charge in a shell examined was found to be 3 lb. 12 oz. 15 drs.

The smoke box, Rauchentwickler Nr. 11 is described as a separate item in this pamphlet.

The gaine in the exploder container is the larger size of the C/98 model with a filling P.E.T.N./Wax (gr.Zdlg. 3/98 Np). Details of the gaine are included in Pamphlet No. 6.
