I believe Edwards made Benton pipes that were house pipes for Iwan Ries decades ago. I bought three of them -- a billiard, a Canadian, and a bent-billiard/almost Oom-Paul, all of the mentioned oil cured Algerian briar, all of which have aged extremely well and look almost new. Today, I'm trying to figure out who the remaining highest volume U.S. briar pipe maker might be. It's between F.M. Frank that makes Kaywoodie, Yello-Bole, Medico, in Windsor, N.Y., and Dr. Grabow in Sparta, N.C. that makes Dr. Grabow pipes. On the basis of availability, I would guess that Dr. Grabow is the larger volume producer, but I have no evidence otherwise. Dr. Grabow's factory took a hit by an earthquake this summer that shut down the factory for a time, but I suppose they have resumed production somewhat by now. I own and enjoy both Dr. Grabow and Kaywoodie and Yello-Bole pipes.
