Just as a point of interest, Some time ago, not that long, I bought a set of the early saddle springs from Paul Houghton who runs a spares outlet for Rudge motorcycles. His website shows a large range of parts and some may not know that Rudge also used Miller lighting gear so he carries some fabulous reproduction parts that will certainly be correct for our pre-war machines. These springs seem correct to me and are counter wound to one another, they are listed at 35 pounds for a pair. If anyone looks up his website you will be quite surprised at what he has and the quality is excellent. Miller diplite switches, early Lucas type horn buttons with the knurled button, Miller 35 E type tailights, etc..........Definitely worth a look...........
