This is a Wessex bent brandy, I believe the style is correct. It is a Klein design, made in France, number 162 if you're scoring at home and it's a terrific pipe. Well drilled and the briar is very hard, the way I like it. The problem, if that's what it is, is that the rim is uneven and retains some char even though I've used everything but a jackhammer to remove it. So the question -- what's the best way to level off the rim, what should I use. I keep hearing pipe mud, which I've not used but might consider. And, if course, there's always the option of leaving well enough alone. Any ideas? Thanks in advance.
