This listing is for a very rare Conn 25 Gold Tone cornet mouthpiece that is in very good condition for being more than 80 years old with a small scuff mark, minimal scratches, dings, etc. And some minor insertion wear, all of which are typical aesthetic issues of vintage mouthpieces. See photos. This amazing mouthpiece still has all of its gold plating. The Conn 25 cornet mouthpiece has a very small cup with a very wide comfortable “cushion” style rim that fits most standard new and vintage cornet receivers. Please see detailed information about Gold Tone mouthpieces that is provided in the screenshot (inserted as the last photo). Please let me know if you have any questions. Please let me know if there are any questions. Thanks for your interest.
