The sloped sided design evolved from pre-1939 private owner wagons built by Chas. Roberts and Co. After the liberation of France 2,500 were shipped over there, 1,900 later returning. Around 10,000 were in stock with BR, with withdrawal taking place in the 1960s. Some ended up private industry use. Transfers for BR. 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.
