This is a Lotus mouthpiece for flugelhorn, model 3XL, with a large shank (Yamaha shank). It's a mouthpiece from Lotus, a manufacturer supervised by Adam Rapa. Production has been discontinued, so the number available on the market is decreasing. This is the third generation, the latest version as of now, with gold plating and a satin finish only on the outer part, not on the rim. It's like new, without the box.
