This entire situation is frustrating.
My perfect pipe is exactly like this pipe: 6" plus, perfectly straight shank billiard. The fact that this is 70 years old, etc., only makes it more appealing. And I have looked for a pipe like this and believe it or not - it doesn't exist. Those that come close either cost $700+ or are too short, etc.
@rothnh - true, the location is at the bottom of the bowl, near the air hole. I can see inside and I see no charring - looks ver ysolid actually. it is possible I suppose that it's a exterior burn, but I would have expected more of it to rub off. If I do keep it, I will probably put a layer of pipe mud or cement on the bottom for added protection.
Well, I will update you guys next week - no matter what I decide, I really appreciate the input.
