Several months ago I purchased a Unison S400 Tenor Sax off Ebay. In shipping the part of the octave mechanism on the body, that sticks up and goes under the octave key on the neck, broke. I have tried googling to find a dealer that might be able to get me the part, but all 3 places I have tried did not get back to me. Also I tried emailing Unison and got no response. Does anyone know where or who can get me the part I need?
