The British 4 inch Stokes mortar round was divided into two general types: the old style and the new style. The new style was very similar to the Stokes round used by the Americans; however, the British used the following fuzes: British Mills Pistol, British Allways or 146 fuze, and the 31-D fuze (used on thermite, heavy smoke and ranging rounds). The complete British 4 inch Stokes mortar consisted of the round body, burster, fuze, propellant charge and filling. The round was a cylinder 4.0 inches in diameter fabricated from drawn steel tubing or rolled metal with an overlapped weld.
