Used small bore (approx 0.480") tenor trombone dating most likely from 1910. Silver plated instrument with tuning in the slide. No slide connection nut. No slide lock. Horn needs work to play - there are some dents in the bell and the slide is very slow though shows no major dents. The in-slide tuning mechanism is missing. A collector's item today, this horn is sold as-is and would be a nice restoration project. Price firm. Includes case. No mouthpiece.
