7C mouthpiece with narrow shank for small 3B bore
The Arnolds&Sons 7C narrow shank is intended for instruments with a small 3B bore. With a mouthpiece, the fit of the shank matters, and this model matches that specific sizing.
The shank start is 10.65 mm, the shank end is 12.5 mm and the shank length is 38 mm. That gives you the exact dimensions when you are looking for a 7C mouthpiece with a narrow shank.
Arnolds&Sons 7C in silver finish
This Arnolds&Sons version comes in a silver finish. It gives the mouthpiece a neat, classic look that suits many brass instruments.
