Kanstul 1688 Trombone with tuning in the slide. .547 bore with Kanstul CR valve. The horn was built for me about 9 months ago. The red brass brass bell is a heavier version than the standard model. The slide is bronze with a nickel end crook. 3 leadpipes are included. The horn is in excellent conditions with no dents and only a few very minor scratches. The slide is very fast and in perfect alignment. A pro-tec case is included. Please feel free to ask questions. I prefer to ship to the US only.
