Adjusted, fully functional. Good airtightness. Piston work is smooth. All slides are smooth. Higher-end model than TR-300. Features engraving on the bell. Inherited by the Vincent model. Intonation and sound quality are not a problem. No noticeable modifications. There was lacquer peeling in places that are touched, but some areas have been coated. Overall, I think it's in good condition. Includes a good-condition hard case. ★Mute and mouthpiece are not included.
