This is a YAMATO three-valve signal bugle used by the Japan Ground Self-Defense Force and the Japan Air Self-Defense Force. Compared to recent bugles, the bell is thicker, making it easier to produce a deep sound. The tuning slide is stuck and cannot be moved. Also, there are deep scratches on the tuning slide, possibly from a previous owner trying to remove it, but this did not affect the sound (tested during several special duty shifts). Since I no longer use it, and it has some issues, I'm offering it at a low price. Before offering it, I washed it with hot water and cleaned it with brass soap, but please understand that it is non-refundable and non-returnable. - Model: Bugle - Color: Gold - Accessories: Case, red string - Features: Metal, smooth finish Thank you for looking.
