This is an older Rousseau from like 10 years ago. From the website of the current version: The Rousseau Classic NC Tenor Saxophone Mouthpiece was developed as a complement to the original Rousseau “R” Series, but it quickly took over as the most popular Rousseau model. When Dr. Rousseau couldn’t find any commercially available saxophone mouthpieces on the market to recommend to his classical students he decided to try and design his own mouthpiece.
