B. Tilz S.B. model mouthpiece for French horn, SB4 size Inner rim: Pink gold - Brand: B. Tilz - Model: S.B. model - Type: French horn mouthpiece - Size: SB4 - Shank: American shank Thank you for viewing. I purchased this new about a year ago. I am selling it because I switched to a different horn and no longer use this mouthpiece. Personally, I found it responsive and easy to hit high notes. There is a slight dent on the rim. Please understand that this is a used item and has been stored at home. Thank you for your understanding.
