This is an iron kettle with the Ryubundo mark on the back lid. According to the inscription on the back lid, it seems to be a gift commemorating the 10th anniversary of the Ikeda Credit Union, but the details are unknown. The iron kettle has a diameter of approximately 15cm, a height of approximately 10cm excluding the handle, and approximately 21cm including the handle. It's a masterpiece with a long history! Thank you.
