English: BR Diagram 1/112 unfitted, all-steel, rivetted, 16 ton mineral wagon No.B192437, built to a Metropolitan-Cammell design by the Royal Ordnance Factory, Dalmuir in 1946 to a Ministry of War Transport order for service in France where it became SNCF No.6.564437. In 1950 BR purchased the wagon which was refurbished by BR’s New Cross Gate workshops under Lot 2286 and assigned Diagram 1/112 (later TOPS Code MCO). BR purchased 7,000 such wagons from the SNCF in 1950 which had regarded them as too small; they were refurbished at BR New Cross Gate and BR Earlestown (which sub-contracted some of the work to Exmouth Junction, Bromsgrove and Barrow repair workshops) although only 6,982 were placed in service, the others being regarded as in too poor condition to justify remedial work. In addition, BR bought from the SNCF 1,892 16 tonners of Chas. Roberts design (with sloping sides), given Diagram 1/100 (1,867 placed in service) and 308 to Hurst Nelson design (305 placed in service) given Diagram 1/113, all originally ordered by the Ministry of War Transport or the succeeding Ministry of Transport for shipment to France after D-Day (which had received 10,000 in total).

Aside from those intended for France, the MoWT and MoT ordered 60,000 from many manufacturers of the three designs in WWII for service in Britain which post war were taken over by the LMS & LNER (5,000) and BR (55,000) which assigned them various diagrams (1/100, 1/102, 1/103, 1/104, 1/105). BR designed their own variant of the steel 16 tonner produced to several diagrams and an amazing 300,000 of these were built in 1950-59.
