This is a measuring board that was on a local bus in America when I was there. At the time, it was made of solid wood and I liked the design, so I asked if I could take it home. I believe it's the only one of its kind in the world. It's designed to prevent fish from sliding off when placed on it, and it looks like it was handmade. It can also be hung from a wall, so it would be a good antique. It's quite old, so I'm offering it at a low price. Please purchase only if you understand American vintage items.
