This item was stored at my parents' house. It seems to have been used once or twice, but was then kept in its box for a long time. Approximate size: Height 23.5cm, maximum width 16cm, mouth diameter 12.2cm, base diameter 10cm. The included brief history states "Showa 36 (1961) Nitten commissioned, Kofukai judge," so it is probably a work from around that time, about 60 years ago. Thank you for looking.
