About 100 years old, in good playing condition but not a modern instrument. 2 tuning slides, one low pitch and one high pitch. Slide is brass with nickle oversleeves, and the brace on the outerslide was left unsoldered so it self-aligns. It works well and will fall easily on it's own but can't be compared to a modern slide. Silver-plated with nice engraving. I used it when I used to do historical instrument demos for school kids. Clean, no smells, original case and suitable mouthpiece. I can text or e-mailed pics, or check Facebook trombone marketplace. $250. I'll cover shipping.
