I recently picked up a Sam Martin estate pipe in great condition. I just cleaned it and plan to take it for a spin today. I’ve searched the forum to see what info/reviews I could get on these pipes but haven’t found much more than they are loved and Sam was loved. Any thoughts on these pipes? Strangely, as beautiful as mine is, there is a black spot on the deeply sandblasted wood that doesn’t look like a stain but something inherent to the wood itself. Very weird! Haven’t seen this type of black mark on any other pipes!
