Wooden Go Board and Stones Set

Thank you for looking.
This is a set including a wooden Go board, black and white Go stones, and wooden containers.

41.8 x 44 x 14.2 (height) cm
(Height with legs is 26 cm)

White stones: 169 pieces (2 chipped)
Black stones: 181 pieces

This is an old item from my grandmother's house. It was a valuable item, and I was told the white stones are made of shell.

The Go stones have been hand-washed with lukewarm water.

The sides of the Go board appeared to have mold, so I have sanded down the noticeable areas. However, complete removal was not possible.

I have wiped it down as much as possible to deliver it in the cleanest condition.

Thank you to anyone who understands that this is a very old item. :)
