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). I no longer use it, and due to the issues, I am selling it at a low price. Before selling, I washed it with hot water and cleaned it with brass soap, but please understand that it is sold as-is, with no returns or exchanges. - Model: Bugle - Color: Gold - Accessories: Case, red cord - Features: Metal, smooth finish Thank you for looking.
