Vintage Salt & Pepper Shakers MCM Zebra Wood Barbados West Indies Sailing

Up for your consideration is a vintage salt and pepper shaker for Barbados, West Indies. They measure 6 1/2" tall. In the last photo I have shown lining on one of the shakers. I don't know if this is part of the wood or a pen mark. It all flows around and looks like it's part of the wood grain, but I'm not positive. There is also a paint chip on one of the sails. It's really a beautiful unique set of shakers.
