Here is a great piece in a 106 version. It is probably in a Gp. 4-5 range and over all a very comfortable piece. This piece came out in a natural, no stain finish. I have not been doing too many of these naturals lately but it looks great with the mouthpiece. The blast is wonderful as you can see and I used some older material for the mouthpiece. I use to use this blue material quite often but I have not used any in some time. I love the look and it goes very well with the natural finish. I use to call it emerald Cumberland but now I use that term for an actual green color Cumberland. This is in fact blue and black. Hand cut Blue Cumberland mouthpiece w/Delrin tennon, hand made solid sterling silver fitment. Thank you very much for looking.
