Just some (slightly) educated guesses: the move to multiple water-bottle braze-ons was gradual. I have an early "true" touring model Holdsworth that only has one bottle mount. Demand for more bottles produced the double and then triple mounts on touring, Mtn. bikes and even some Tri bikes (always wondered why you'd want extra water on a triathalon). This model was probably considered a Sports Tourer, so one that would be used for shorter faster trips and less luggage, including fluids. A true full touring rig would probably have cantilever bosses, 40-spoke wheels, even longer wheelbase and a lower BB. Caveat: there are many exceptions to all the above "rules". One more: I have bought 5,6, and 7 spd. freewheels from Nashbar, and certain of their housebrand FWs were OK quality, but I got some cheap Chinese junk that was truly horrible, so quality varies depending on where they sourced the FWs of a particular batch. The Indonesian Shimano that Sheldon/Harris sell seems to be much more reliably good quality, IMHO and limited experience.
