Details: This is a well-made choukan probably near WWII vintage with a kinko style buffalo horn utaguchi inlay and urushi nakatsugi rings. Because of its overlength by 9 bu from the ideal 2.0 size, it plays slightly flat of C 440 but is well in tune with itself. As seen in the above picture, there was a crack running down the back side from the utaguchi, but repaired with staples, rattan binding and urushi. I doesn't seem to have run through the bore. As you can see, the staples is an old way of binding cracks. the crack has been stable for a long time and doesn't affect playing.
This choukan has an expressive and full tone. Very playable.
