Almost 2,000 of these wagons were built between 1924 and 1929. The design was one of the first produced by the GWR using Railway Clearing House spec brake gear. Many survived into 1960s. 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.
