I just completed this piece and it is quite the handful! At least a gp. 6 but a squatty, stout piece. This billiard, or stack if you prefer came out with an awesome blast, slightly rounded top and generious capacity. I made a half saddle mouthpiece which I do not often do. With the half saddle it makes for a comfortable piece in the mouth the pipe also feels great in the hand and it is a sitter. Hand cut Tan Cumberland mouthpiece w/Delrin tennon. Hand made solid sterling silver fitment. Thank you very much for looking and your consideration of my work.
