I have added images. 2024.07.05 In the 16th image, I've slightly changed the three holes to a staggered pattern. I have used this instrument for many years in stage performances, accompaniment for competitions, etc. I am selling it because I am purchasing a new instrument. I believe the sound starts beautifully, which may be due to the shape of the end (bell) of the instrument. This is an early work by the renowned maker Seiwa. The mouthpiece cap is size 5. It was quite expensive when I bought it. I have been actively using it continuously since I purchased it.
