If you've happened upon my little half-acre of webspace and perhaps been disappointed that my 1971 Columbia Sports III isn't exactly all that old, here's a link that should fulfill your old bike fix.
From their website TheWheelmen.org:
The Wheelmen is a national, non-profit organization dedicated to keeping alive the heritage of American cycling, promoting the restoration and riding of early cycles (1918 or earlier), and encouraging cycling as part of modern living. Members are intent on learning lost skills, retelling lost stories, researching and writing of the golden era of cycling.
As for my own best efforts, they're on hold this week until I can get to the hardware store for a bigger wrench. Then, look out!
