Got the PM.
Hi Orlandofurioso, and thanks for the kind words, Jesse. :D
Sorry to hear that the Barling has some worrisome condition issues.
Specific recommendations aren't possible without having the pipe in hand, but the same principle applies to all collectable antiques: Pretty much anything CAN be done to bring them back to near-original condition, but the more that IS done the more it will cost AND the return on that cost (in terms of resale value) will diminish asymptotically.
Pipes are one of the few old collectables that can be (and often are) regularly used, though, which can change things a bit.
So, Orlando, what is your intended "mission" for the pipe? What attracted you to it, and why did you buy it? Understanding that is essential to knowing how to proceed now that you have it (and returning to the seller is an option).
