Sorry to keep this off-topic nonsense going, but I have to chime in with the fact that in England many of the finest classic lightweight bicycles are traded rather inexpensively among the group of several hundred members in the Veteran-Cycle Club. The bi-monthly newsletters include a rather extensive classified section and most of the stuff is expected to trade hands in person at regional cycle jumble events. Some of the most experienced eBay UK purveyors are clearly making sizable profits by attending such events and bringing the bicycles and components into the public view for perhaps the first time since new in the 1930s-'50s.
