Riley Pathfinder (RMH). (1953-57)
The Pathfinder was designed as a credible replacement for the strong-selling, in Riley terms, RMB/RMF series. Officially termed RMH (RMG was to be the RME's replacement), but renamed Pathfinder - Ditchfinder by owners... - by BMC. At the same time, Nuffield (the project was planned before the BMC merger) was trying to rationalize, by designing one car, and selling it as both a Riley and Wolsley (The 6/90).
The car was launched in 1953, and sold 5152 examples until 1957, but didn't reach BMC's expectations. One problem was that the Riley and Wolseley models both had different engines, gearboxes and trim, making the car overly expensive to produce.
This resulted in a minor facelift, and the insertion of the BMC C-series 2.6, 6-cylinder engine, instead of Riley's Big-Four engine. This created the Two-Point-Six of 1957.
