I bought this pipe on the chance it might be an old CPF or something similar. I always like a nice Bakelite stem. The first thing I noticed was that the bowl has a centered draft hole. And after a little cleaning, it appeared to be a metal washer. Strange! Then I noticed that at the bead, the top part of the bowl seemed to overhang the bottom on one side. That's when the light bulb went on over my head. The bowl must be removable! I had never seen a Meerschaum exactly like this before. The next question was: Is it threaded or not? It took a while to break it loose, it turned out to be simple pressure against a cork ring. Since taking these photos I've replaced the cork. The original stuff dried out and gradually crumbled. And it smokes surprisingly good.
