This is a brand-new Schilke ST21 large bore tenor trombone with a hagmann valve. It's only been played about 5 times. There isn't a dent or scratch on it. It plays great! I especially like the hagmann valve. It's a much more consistent sound than the Thayer or rotor valve and it engages faster. It comes with a hard-wood Edwards case. The case has some wear and tear but functions well. I'm selling it because I no longer play. They cost $3,495 new. I'm asking for $1900.
