I have recently aquired an S. Bang Giant smooth. Pre84. I love the pipe. It has a large deep bowl and smokes great! However there is an issue with the stem. On the lip dead center on top and bottom is a very small crack to which someone took a file. Now I can smoke this just fine as is, and very well might just do that. But, lets assume I wanted a new stem just to bring back the glory of this pipe. Where would one go to get this done where you can trust they will take the care and attention to detail that an S. Bang deserves. I tried emailing S. Bang about my issue but there was not reply. Any ideas for a trusting quality fix for this side of the pond?
