*Marble / Onyx Chess Board Vintage Double Sided - Full Set

This is vintage chess I’m guessing from 1960s to 2000s I’m not sure. I have no idea what brand or model or exact year it was made. I see exactly same one selling for $230. The chess is 3 lbs and the chess and the set is 5.2 lbs and length and width are 9 1/2 inches and top left corner to bottom right corner is 13 inches. It’s a beautiful chess. It some flaws some scratches some scuffs so what you see in condition is what you’ll receive. Thank you.
