If you want to restore your own, PM me. I can provide some links.
That said, unless you're super handy, don't mind doing a ton of research to do it right and -- most important -- you absolutely love doing it yourself -- let a pro restore your prized estate pipe.
Walker does great work, as does Norwood's Pipe Repair and MKELAW Pipes. Personally, I've had Bob Clark at Clark Pipes in RI repair a pipe for me recently and I'm very pleased with his work (tell him Rich sent you).
