This oil tank wagon consisted of a tanker mounted on a four-wheel chassis. The tanker had a flip-top dome casing on the top, bracing in two places around the tanker, mounted on an underframe.
Some were painted yellow with red stencilled lettering of Shell, the oil company. Others were black, with white stencilled letters. The chassis was bronze coloured.
Additional detail included a moulded hand brake on the chassis.
