Up for sale is a Schilke S21 Trombone with a Hagmann valve. The bell is in yellow brass. It’s a .547 bore horn with a wider slide like Bachs. The slide is yellow brass with a nickel crook. The horn is clean overall with a dent on the cross brace between the bell and where the slide connects to the neck pipe (see pic 2). The slide moves freely and so does the valve. More pics available upon request. Comes with 2 stock leadpipes.
