This is a MINT King 1140W 3/4 size top action 3 valve tuba. With short action valves, these American made instruments offer low sound at a great value. Original case is perfect and included. This model is playable as a concert tuba but is also convertible for over-the-shoulder marching. This instrument is in perfect condition-ostensibly a demo model, I see no sign it has ever been played. Pics tell the rest of the story! Please feel free to email with additional questions. Bid early, bid often!!!
