This shell is fired by the 4.7 cm anti-tank gun mounted on the S.P. armoured chassis I B.

It is a normal armour piercing shell with an H.E. capacity of 1.6 per cent. The filling con-sists of a 6.6 dram bursting charge of cast T.N.T. with a 5.3 dram intermediary of pres-sed T.N.T. The intermediary pellet is wrapped in transparent paper and has a cavity to receive the gaine portion of the fuze. A cardboard disc in the cavity and a washer in rear of the pellet provide seatings for the fuze and presumably allows for tolerance in the length of the filling and the fuze.

Empty shell, 1283.25 grams (2 lb. 13 oz. 5 dr.).

Cast T.N.T., 11.7 grams (6.6 dr.).

Pressed T.N.T., 9.35 grams (5.3 dr.).
