Tuba Mouthpiece Atelier Momo Arnold Jacobs Model I bought this from an acquaintance about 10 years ago. I used it for about 4 years on a BE-995. It has been left unused for about 6 years, so it has deteriorated significantly. I, as an amateur, polished it quite a bit, but as you can see in the photos, there is still a lot of dirt and grime. Please purchase only if you understand the condition. It will be shipped in bubble wrap and a box.
