The 14 ton slope sided mineral wagons were designed and patented by Charles Roberts in 1935 and prior to the war many could be seen in Private owner liveries. The MWT (Ministry of War Transport) ordered 9,000 wagons in 1943, however only 7,000 were completed by nationalization. B.R. later designated these wagons to Diagram1/100, and uprated them to 16 tons. Four further batches were ordered in 1946 with many lasting into the 1960’s
