Small Bronze Bowl with Fish

I inherited this small bowl around 40 years ago; I have no idea if it is older than that or not. It's 3 inches tall, and approximately 4 1/2" in diameter, and I believe it is made of bronze. There are 4 fish and 1 scorpion along the upper outside rim, as well as ribbing in patterns all over it. The bottom has circular ribbing along the edge, and a ribbed cross in the center. The inside of the bowl does not have any decoration.It looks like folk art of some type — African? — as it's quite rough and the figures are stylized. I've always been curious about it!
