Paired in 1923 using a new bogie underframe from the Metropolitan Carriage & Wagon Co., Ltd., of Saltley in Birmingham using the bodies from 1873 four-wheel carriages A.7 and C.10, in this form the carriage remained in regular traffic until withdrawn in poor condition in 1974; it then entered storage and had its doors removed, the carriage bodies being in poor condition they were removed and it became a bogie runner from 1981.  Following the rebuild of F.9 which was completed in 1991 this carriage was selected for rebuild which was completed in 1999, it being the final carriage to enter traffic in the then-standard purple lake livery.  Each of the first class compartments have mirrors, each of which bear the legend I.M.R. in the style of three of the Big Four railways of the United Kingdom; it is unique among the pairs in having a guards compartment, being an identifying factor when it was selected for restoration.  It is in regular traffic today.
