Seventh of the series and supplied by the Metropolitan Carriage & Wagon Co.,Ltd., of Saltley Works in Birmingham for the 1873 opening of the Peel Line, from 1882 this carriage was close-coupled to B.8.

In 1925 the two were mounted on a new bogie underframe to become “pair” F.50; the bodies were scrapped in 1967 at St. John’s Station and the underframe became R.13, later reverting to their original number.
