-SG- Here's a scan of the only leaflet I have ever seen of the Sturmey-Archer footchange. It was published end 1931 judging by the text. The earliest S-A footchange, as fitted to the works 1929 CS1s, differs considerably in that it relies on the existing disc type control parts for actual gear selection rather than the substantial and more effective spring loaded plunger (part BS132) used on this later design. The 1929 version was prone to heavy wear and the only one I have had anything to do with needed a lot of work to get it to function correctly - and stay in gear! I do not think there was a leaflet on this early version but if anyone has one - or a copy - please get in touch with us.
