OBTW, the shop I bought it from, Clever Cycles in Portland, Oregon, said that they could tell which craftsman built the bike by the look of the brazing. They also said that a signature of the builder was somewhere. I meant to ask where, but over the course of the hours that it took me to test ride everything and make a decision I forgot to.
But, if a machine now does the brazing maybe they can't ID the builder anymore, or maybe that was just a story...?
