sought-after ! Antique Shogi board

I'm not sure exactly when it's from...
My mother told me she received it from her uncle, who used to run an antique discover a long time ago.
Since my mother is elderly, it's quite old.
It has a heavy feel to it, and while it has various scratches and dirt, it has a attractive black luster and a commanding presence.
I brought it home when we cleared out my parents' house, but I don't need it, so I'm offering it to someone else.
It's chic simply to have it on display.
There's a faint, round stain on the surface. Please check the photos.
I hope someone will appreciate it.
Thank you.
