It sounds like Aydlott's is the answer, but I can see how it would be confused with a Sav, with the type face of the stamp and the patch of smooth finish for the stamp, very like Savinelli does things. It's just that Sav doesn't do seconds so much, or rather, they tended to route their seconds out as unfinished pipes, some stamped but most not. Today I think they route some of these to be finished as Rossi pipes, which are often excellent smokers and visually flawless. I have a Palermo zulu 404 and a prince Rossi, and they are indistinguishable from Sav's for smoking purposes.
