These coaches were built for general service and were the most common Gresley brake thirds. Variations existed in the arrangement of the stepboards and you should rely on a contemporary photograph if you wish to model a particular vehicle. Those built before 1931 had turnbuckle underframes (Comet pack C31); later builds had angle iron trussing. As a rule, the grab handle adjacent to the guard’s ducket was fitted in the lower position. Alternative locations are indicated by half etched dimples on the reverse of the upper section of the coach side. Many saw wartime WD service and some were converted to Carflats in the 1960s.
