This mark is on the bottom of my Grandma and Grandpa Cream and Sugar Set. Thank you for any info you have on the date and/or manufacturer. [img size=288]https://kovels.com/media/kunena/attachments/legacy/images/MARK_MADE_IN_JAPAN.jpg[/img]
made in Japan was used after 1921. In my made in Japan books it can’t be determined the exact date, but it does list Iwata as the manufacturer.
