Stork French Horn Mouthpiece M7 This is the model of Philip Myers, a legendary player from the New York Philharmonic. Inner rim diameter: 16.7mm Throat: 5.2mm Deep cup Very thin rim With a very small rim, a deep cup, and a wide throat, it has a unique, elongated shape. When you play it, it produces a delicate and deep sound reminiscent of Myers, which is enjoyable. Needless to say, it's highly recommended for those who like the beautiful American sound of players like Myers, Myron Bloom, and Cherminaro. I couldn't handle it myself, so it's been put away, but I hope to pass it on to someone who can make good use of it.
