Hi all; can anyone give a year for the introduction of 531c tubing? Or point me to a site with Reynolds info or timeline? I know there are several styles of decals (for 531c), mine is probably the earliest. Here is a pic: http://www.wooljersey.com/gallery/Freeks-racefietsen . The forks have shield decals, not triangular; they just say '531 fork blades'.
Take a look at the decals in this auction. The auction says this Special Lightweight tubeset was later called 531c. I thought there was a subtle difference between 531c and 531SL, but I don't recall what it was. Anybody know? Lou Deeter, Orlando FL
