French horn mouthpiece, B. TilZ's E. Schmid9 model. Specs are as follows: Cup inner diameter: 17.5mm Cup depth: MD (Medium Deep) Shank: American shank There are some scratches on the shank from use, but there are no distortions or dents, and I think it's in reasonably good condition. It is said to be a good choice for beginners, and has a deeper cup than the recommended 8, so the throat diameter is also wider, and the breath flows smoothly. Also, the tone becomes thicker, and although a lot of breath is needed, it was much easier to produce a large volume compared to the 8.
