Sturmey Archer's hubs in the 1940s and 1950s used two types of sprocket ­ screw-on mostly on their basic AW and AB, FWs, etc and a 12 spline sprocket on their upmarket hubs FM, FC, ASC, AC etc. This was also used on their pre-war 2-speed fixed hubs TF, TFB, T and TC, and the 3-speed KS and KSW hubs. The familiar 3 spline sprockets were fitted from 1957 onwards right across the range of hubs. But the pre-war hubs can only use the 12 spline pattern ­ this isn't strictly true as the 3-spline sprockets can be modifified just a little with a Dremel and fit on the 12 spline drivers. Post war hubs can have their drivers changed for later 3 spline drivers and that is a very simple operation. Troy, I amost certainly have a spare 18T sprocket and will take a look tomorrow at exactly what I have and email you. Regards Hilary Stone
