Not only do people disagree on identifying pipe shapes but sometimes the manufacturers and/or retailers change the descriptions over time. About ten years ago, I really liked a particular shape of Peterson, so I bought two of them -- a Shannon and a Killarney -- from smokingpipes.com. I'm sure at the time they listed the shape as a brandy B11. Today I happened across this shape again, just to see if it was still available, out of curiosity, not needing another. And lo' and behold, pipesandcigars has it listed as a volcano! But the B11 designation remains the same. Any similar experiences with shape-shifting pipe descriptions/designations?
