It's a new and perfect instrument, not a demo. Conn 5G mouthpiece, case, and factory warranty are included PLUS our two-year service warranty. 
 
The Conn 88H was introduced in the early 1950's and quickly became one of the most popular large bore tenor trombones with F-attachment, endorsed by professional players worldwide. It's still in production today, the benchmark by which other trombones are judged.

Specifications: .547" primary bore with .562" bore open wrap F section, 8-1/2" rose brass bell, rose brass outer slide, clear lacquer.    

The original Conn 88H trombones had traditional wrap F-attachment. This one is the "modern" version with open-wrap F-attachment and thin red brass bell (like the originals) for easier response in all registers.

With Conn 5G mouthpiece and deluxe Conn hard case.
