The RMF replaced the big RMB limousine in 1952. It shared that car's 2.5 L "Big Four" engine as well as the mechanical updates from the RME.
The RMH Riley Pathfinder, the last automobile to use the Riley "Big Four" engine, and thus considered to be the last "real" Riley by purists, took its place after 1953 and continued in production until 1957.
