This is a rare KING tenor trombone, the "3B CONCERT"! I've done some research, but I've never seen one with this engraving. [Product Condition] There are minor scratches and small dents due to age, but there are no major dents or damage that would hinder playing. It's a gem that can still be used for a long time. The slide and tuning slides have been adjusted for this sale. It sounds amazing!! The original case is included. This is a rare item, so please take this opportunity to purchase it. Please check the photos carefully. Although it is a good product, please understand that it is a used item before purchasing.
