I just completed this classic Dublin. On the taller side and it reminds me of an old Charatan I use to have. I would say in the Gp. 4 to 5 range and it is a flat bottom sitter. Very slight bent and very comfortable. Hand cut Neon Cumberland mouthpiece w/Delrin tennon, hand made solid sterling silver “Wide Flat” fitment. Thank you very much for looking and your consideration of my work.
