A nice sized classic Billiard with my Grey Cumberland.I woudl say this piece is in the range of Gp. 6 or even ODA. I really like this material as it is different but staying with the traditional look. I am very pleased with the way this piece turned out! I really love the feel of this piece, it just feels so comfortable to hold but then again I am partial to Billiards. I discovered a superior technique than I have been recently doing for thinning my mouthpieces and I am very happy with the thinness and comfort. I will continue to do this to my mouthpieces. This piece is rusticated then sand blasted which results in a incredibly deep, craggy, almost coral like appearance. The rustication along with the rings from blasting it truly is an interesting finish to admire. Hand cut Grey Cumberland mouthpiece w/Delrin tennon, hand made solid sterling silver fitment.
