I have had this pipe for some time and I have never been able to identify. Wondering if anyone has seen or heard of "Tower of London" pipes. I am thinking GBD or Charatan briar for a pipe shop of that name? It is a very large bowl (size of a Peterson House Pipe) with beautiful birds-eye and cross grain and only one minor flaw in the briar that I can see. In the end just a great pipe but thought some history might make it that much more fun. If you have any info I would appreciate it.
