I immediately wondered about the date/era of your pipe. I've always avoided BBB pipes because I've never seen a definitive method for dating the various eras. The Pipedia entry, link below while interesting, assigns no dates to the various era's (Own Make, Best Make, etc.) Google wasn't of much help either, folks just constantly reference this article.
