Almost 1,000 of these high capacity wagons were built in the 1920s for Welsh coal traffic. Rerated to a 21-ton capacity wagon during the Second World War, they were in traffic until the 1960s. Transfers for GWR and BR, and for Norths Navigation Collieries. These finely moulded plastic wagon kits come complete with pin point axle wheels and bearings, 3 link couplings and transfers. This kit is supplied with pre-coloured moulded parts although painting can improve the appearance. Additional parts to enable the vehicle to be modelled incorporating modifications made to the prototypes during their working life are included where appropriate.
