This particular instrument had some minor damage to the bell which has since been repaired but is no longer in perfect condition cosmetically. See last image for damage. 

Yamaha Trombone YSL154 Silver - DISPLAY MODEL, the ideal instrument for the beginner and student. Like all Yamaha student model instruments, the YSL154 trombone is designed especially for the younger player (not that an older player won't benefit or enjoy it either) in that it is lighter and very durable. 

A lighter instrument will allow the student to control the trombone better as they play. This allows them to focus on the music and not struggling with holding the instrument.
And as with other instruments from the Yamaha student range, the YSL-154 trombone offers accurate intonation and a rich tone from the start. A great start to the instrument will inspire the student to work harder, because they'll hear the results. 
The supplied Yamaha mouthpiece is also designed to enhance the playability of the instrument, offering greater intonation and control than other mouthpieces in this price range.
