Mahjong tiles, wooden box, extremely rare antique

Mahjong tiles, a wooden box with drawers.I believe this antique has been displayed on the floor since my grandfather's time, but I don't know the manufacturer or the age. It has been stored for several decades.The tiles seem to be complete, but since I don't play mahjong, I don't know how many betting sticks it originally had.The drawers can be pulled in and out, but some of the handles are missing parts. The outer box is quite chipped and cracked.The front lid is present, but the tenon is broken, and it comes off when the string is untied.Please consider the photos for your review. impeccable for everyday use. supreme materials and excellent craftsmanship ensure long-lasting durability.
