The RM series was introduced in 1945, just after the war and it was one of first real new post-war models, with a separate body fitted to a rolling chassis, but with some nice features such as hydraulic brakes and torsion bars, rather than the traditional leaf spings.
The first versions were the RMA and RMB, whereby the main difference lay in the different engine types, with a 1500 cc 4-pot for the RMA and 2443 cc four cylinder for the RMB. Outwardly the difference could be spotted by the longer hood, needed to accommodate the larger engine, for which a 6.5 longer wheelbase was required. Furthermore the badge had a different colour shape….
In 1952 the RMF succeeded the RMB, it had a better chassis and improved brakes, but outwardly the differences are unnoticeable. Production lasted only one year, and only 1050 RMFs were produced.
Shown here is a highly original example fitted with a factory made sliding roof, which made its appearance at the LeMans Classic in 2006.
