It is frustrating, isn’t it? I believe the trademark was registered on October 9, 1917. Bill Feuerbach believes Kaufmann, Bros. & Bondy phased C.P.F. out around 1915—a 1924 KB&B catalog shows KB&B Chesterfields (maybe Yello-Bole, too?) I have a C.P.F. Chesterfield and KB&B Chesterfield—I don’t think I have one stamped with both logos (though, I’d have to poke around to be sure). The window of production is most nebulous. I have some C.P.F. pipes with Redmanol/Bakelite stems; I believe Redmanol was formed around 1913—in 1922, the Redmanol Company, the Condensite Company of America, and General Bakelite were consolidated into the Bakelite Corporation. So, whenever I list some of my Colossus Pipe Factory pipes, I usually write “circa 1921” to bridge the window between 1915 and 1924. I wish there were more details with regard to the timeline with the Grand Street and 17th addresses KB&B had.
