Scott--- FYI, the page at
Page Not Found lists T1 and T2 as the original intended products for WG1 and WG2. From everything I've read on Greytalk, WG1 and WG2 are actually the two books in the 1983 Greyhawk box set, with S4 being the original WG3 (as you state). I don't know the source for this info, but here's a link to the various discussions about WG1, etc. in the Greytalk Archives:
