Good luck, the Rudge is a find, been looking for one myself. E3Ss are fun to ride and while the purists do not call them English Racers they were certainly racier than the ballon tired bike the other kids had. And no, we were not so ignorant that we thought them actual racing machines.

I think the Rudge are sought after because they were higher end bikes, well made and relatively rare at least here in North America.

I like to set my E3S up a littler racier though than most with the bars tops well below the saddle crown. Feels good with better control and still very comfortable for viewing the countryside at gentle speeds.
