Conn 50H F attachment trombone *used*

This student level trombone has a medium-size bore (.522) and will use a small shank mouthpiece.  The bell is yellow brass, with an 8 1/2 inch diameter.  The instrument is in good condition but shows some wear and tear; there are some scratches and wear of the lacquer.  The slides and rotor function well.  This instrument would be a good option for a student wanting to advance to a trigger trombone, but still want the feel of a smaller bore instrument.
