Thanks for the compliments on the work that I did on those SLDB model descriptions. Most of it was compiled from the catalogs, but some of it was what I thought I "knew" at the time. It was a long time ago, and I now know that some of that info is wrong. You probably have run into some of that bad info yourselves.
The whole thing really needs to be rewritten with better/correct info. Metacortex, with his encyclopedic knowledge of all things Schwinn, is the obvious choice for the person to do it if he would be willing to take it on.
In at least one conversation I've had with Bob Hufford, who first created the SLDB, he expressed his wish that at some point it would be passed on & taken over by Metacortex. I am all for that!
