Thank you for viewing! This is a mouthpiece for a French horn. I used it for over a year, but I'm selling it because I started using a different mouthpiece. It's a very popular mouthpiece, suitable for all-around use, and is recommended for beginners to start with. - Model: HOLTON-FarkasModel MDC Silver Plated (SP) - Shank: American Shank - Cup: V Cup - Cup Inner Diameter: 16.21mm - Bore: 4.62mm There are some scratches here and there, but they don't affect the playing feel. Please check the photos for details. It will be wrapped in bubble wrap and shipped in a plastic case.
