BACH CORP. 7C Small Shank Mouthpiece. This is a small shank mouthpiece for trombone and euphonium. There are scratches and dents on the shank, but it is relatively clean. If you are nostalgic for this vintage item, please refer to the photos and bid with your understanding. When I actually played it, there was no discomfort, but those who are concerned about the appearance should refrain from bidding. Please refrain from bidding if you are looking for a perfect item or are very particular, as it has been stored at home for a long time. Thank you.
