This style of coach is classified by Lewis as LA0MW. In total there were only 8 coaches built to this style and they initally formed one train. Consequently there were only 2 brake coaches built, each to a different design in 1884. They were given diagrams T61 and T62. Both were 31' x 8'6". I've yet to track down a photo of either of these coaches. These are my drawings of these designs based upon information in the Lot Book at York.
