I'm not sure when it came into our possession, but this item has been in my home for a long time. I am listing it on behalf of my elderly mother. I believe it is quite old, so I think of it as an item for viewing or collection rather than for practical use. The underside of the lid is marked with "Ryubundo Zo," and the knob has a distinctive design. Also, there is a shape like a crest below the spout. I have no knowledge of iron kettles. Therefore, I recently asked a major brand-name goods buyer to assess it, and after a photo appraisal, a specialist in antiques at the store conducted a detailed examination. The listing price is based on the appraisal amount at that time. I have listed it hoping to sell it at a reasonable price to someone who appreciates it. Thank you for looking.
