This is a Griego Artist Series (for large shank) 55 mouthpiece. It is silver-plated. Unlike the Artist Series, which is the signature model of Alessi, this model was developed separately with the goal of a mouthpiece that is clear and has stability and control in all registers. Model: Artist Series Tenor Model 55 Cup Inner Diameter: 25.96mm Throat: 7.09mm This is a used item, so there are some signs of use, such as insertion marks on the throat, but it is relatively clean. Also, this item does not come with a box.
