This 7mm. coarse-scale MR Diag. D342 Coke wagon fleet number 66940 was built from the Slater’s kit. The model is in good running order and little-used condition. Metal-tyred Slater’s coarse-scale wheelsets are fitted. The couplings are sprung and two buffers are sprung (located at diagonal corners), whilst the other two are fixed. The paintwork is lightly weathered and there is a full coke load.
