Yamaha 9E Cornet Short Mouthpiece - Type: Mouthpiece - For: Cornet - Short Thank you for viewing. This is a Yamaha cornet short mouthpiece. I used it about 30 years ago. It's a rare model number, so I think it's a valuable item. I haven't used it at all in recent years, and there are no major scratches or stains. It has been cleaned, but please understand that there is some aging due to the passage of time. Shipping via Rakuraku Mercari (envelope)
