I happened upon this Kaywoodie Atlas auction today on Ebay, just as it ended. I've been looking for an oversized Kaywoodie for a while, but they rarely turn up on Ebay (or elsewhere). The seller was Don Warren. It looks to be in pretty good shape, a push stem (minus the stinger apparatus). He says it is a 1950's pipe, but with the four digit shape number, I suspect it might be older. I didn't find out much about these over sized Kaywoodies, save a few lines on Chris Keenes Kaywoodie page.
