This is a King 3B Silver Sonic trombone, famous for its use in jazz. It's a rare model with a phoenix engraving on the bell. The condition is mint. In my personal opinion, there are no noticeable dents or scratches, and the slide tips are also dent-free. I believe it's unlikely to find another one in this condition. Therefore, the price is high, but I think it's a reasonable price for King trombone collectors. Regarding the photos, a balancer is not attached, but it will be included with the normal balancer when shipped. The balancer medal (the King crown mark) has a scratch from when it was removed. If you wish, I can replace it with another balancer medal that has no scratches and attach it to the instrument before shipping. The case is not the Shiny case shown in the 8th photo, but the original King coffin case will be included. As you may know, it's not very practical, but it might be good for those who travel by car due to its robustness. A mouthpiece is not included, but the Silver Sonic cloth shown in the 8th photo will be included (unused). The blue DAC instrument body protection and slide protection cloth bag is not included. The included items are the instrument body, the King original case, the cloth, and a pennant. Please be aware of this. Due to the high price, please understand that this is a no-claims, no-returns sale. The price has been significantly reduced. Please consider this.
