I ask this question because I recently purchased a 1965 Dunhill from Mike at Briar Blues and it smokes like you would not believe. This pipe is so much better than every pipe I have ever owned over the past 20 years (my pipes are not drugstore pipes but Petersons, Savinellis, Barlings, and artisan pipes) that I cannot even put into words just how good it is. It has no discernible wear in the bowl, the stem is like new after Mike's polishing, and yet I know after conversing with Mike that it was smoked a great deal in the 50 years before I bought it. I don't know if it is the briar, the construction, or what but this one is amazing. How can a pipe still perform like this at a half century in age?
