Yes, Mark... the FW is another good candidate but... I don't find that's very often available say on eBay. It was not fitted as a stock hub to any of the Raleigh-Rudge-Humber machines.. the de luxe Tourist and Sports roadsters had four-speed FG dynohubs and the Lenton-Pathfinder-Clippers had FMs. Now, my 1948 Clubman has an FW but of course that was a year before the alloy shells. Anything that was stock on a Raleigh Industries machine is "common"... they had no equals when it came to turning out the goods! And when it came to club and racing machines, they were also just about the only firm to spec hub gears as standard in the 1950s.
