This 7mm. finescale Anglo-Persian Oil Co. Ltd. 10T. Twin Tank wagon fleet number 2538 in black livery is built from a whitemetal kit with brass tanks. The model is in good running order and little-used condition. It has 3-hole disc wheelsets, and buffers and couplings are sprung. These prototype Twin Tank wagons were probably built by Cravens of Sheffield and fitted with steam coil heaters to assist unloading heavy oils and bitumen.
