This oil tank wagon consisted of a tanker mounted on a four-wheel chassis. The tanker had a manhole with hatch 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 tanker was larger in the early production, coming in a slightly smaller size later on. The mould used was the same for the B.P. tank wagon.
Additional detail included a moulded hand brake on the chassis.
The chassis was bronze coloured.
