True blessing B-88O Tenor Trombone with Open Cover F-Attachment. Has case, Blessing 61/2 AL-L mouthpiece, and upkeep add-ons. Single owner given that 1996. Played in jazz and show band just (no walking). There are two very slight dings in the bell that didn't photograph well. The trigger and spit shutoff have both been soldered back on the body/slide. Slide number 475461. I have actually had maintenance corrected the years on this horn. This is a. 547 birthed horn that is largely known as one of the finest beliefs in large-bore tenor trombones, and is based upon the Conn 88H. It's the excellent upgrade for the significant student.
