This is the standard SYMPHONIC model. Compared to the regular 1-1/2C, it allows for much easier breath and sound production. It is silver-plated. While there are some scratches around the shank, it is otherwise in good condition. The original box is also included. Below, I have included the specifications and description. The rim and cup shape are the same as the 1-1/2. Throat No. 24 (3.86mm) Backbore No. 24 ("Symphonic" dark and large sound - most popular special order, standard for A cup) The popular model from the made-to-order "Special Order Mouthpiece" series has become a standard as the "Bach Mouthpiece Symphonic Model." The expanded throat section provides a richer tone, greater volume, a different response and playing feel, and improved intonation. <Reference> The new price for a silver-plated model is 15,730 yen.
