Used Conn 50H trombone. The 50H is a great step-up model trombone with a .522″ bore, 8 1/2″ bell and F-attachment. This horn has a silver plated finish and while there are a couple of places where the finish is a little rough it is in very good overall condition. Upon receiving this trombone our repair tech did a bit of slide work and the slide works great. Included in the price is the original hard shell case.
