This is a new Miraphone rotary valve Eb tuba, model Norwegian Star. Condition is new, unplayed, except it was damaged in shipping. The bottom bow had a medium dent. It's mostly repaired, but a small amount won't come out due to the stiffness of the nickel bow guard. It's not a big deal. The dent action caused the 4th rotor to be scratchy. I'll have that repaired - it'll be silent and good as new action. Available in September.
