This is Bach's second-largest mouthpiece. Because it's a recent model, its specifications are not significantly different from the catalog specs of older Bach mouthpieces (cup 32.75mm, throat 8.3mm), so you can expect the same playing feel as the specs suggest. The inner rim is round, but the rim itself is flat, giving a good response and resonance. It's a bit heavy, like a responsive Berg mouthpiece. There is some discoloration and fine scratches, but no dents, and it's in very clean condition.
