Up for sale is a rare Rudy Muck Citation Jazz Tenor Trombone. Rudy Muck had an instrument shop close to Bach in NY and built trumpets from Bach parts.  He also made a few trombones. The bell section is in very good condition.  The slide mates to the bell but does not thread all the way.  The slide is probably not the original slide.  Comes with a large coffin case.  Insured ground shipping will be $59.  Continental USA buyers only please.
