I bought this go board ~20 years ago from a Japanese second hand goods store. I'm not sure what kind of wood it's made of, but probably katsura or maybe kaya.
The board is 16 1/8" wide, 17 3/4" long, 3 5/8" (92mm) thick without the legs. The legs are 5" (125mm) tall, not including the part that fits into the board. The board + legs + cover weigh ~22lbs (10kg), and packaging will add a couple more pounds for sure.

Make me an offer. Payment will be the offer + actual shipping costs from Lexington KY USA. I prefer payment by US postal money order, but would also do a credit/debit card via Square for an additional 3.5% which is their fee. Paypal is evil, so I would not like to use them.
