BENGE Trombone Mouthpiece - Narrow Bore This item is a discontinued model and is difficult to obtain. There is a deformation at the end of the shank. It might be a bargain for someone who can repair it. I think it's suitable for Jazz performance. - Material: Silver - Type: Trombone Mouthpiece - Design: Standard design with a narrow shank - Finish: Polished surface Thank you for looking.
