BR built 875 of these wagons between 1954 and 1960 for use on the West Country china clay workings. The first 100 wagons were unfitted, but all were later fitted with Morton vacuum brakes. Transfers are included; glue and paints are required to complete this model. Use the Pecoscene PS-361 China Clay Dust Weathering Powder to give that 'working vehicle' look to your wagon.
The body design of the BR clayhood is almost an exact copy of the GWR O13 design china clay wagon. You can backdate easily to the final GWR type by replacing axleboxes or using a GWR 9ft wheelbase chassis kit.
