This instrument is in great used condition.  I'm unsure of the exact age but I estimate it to be 15 years old.  It has a left F and low Bb but no third octave key or C#/B connection, and it has a plateau key for the right hand third finger.  It is clean and comes in it's original Yamaha case with vinyl case cover.
