For your consideration, here is a Vintage Boy with Hat Rocking Horse Plastic Toy Rattle. It is not marked with a maker. It is 6 1/4 inches long. It has some wear on it and the white plastic has yellowed. There is a dark mark on the bottom rocker part. Item pictured is the actual item up for sale and comes from a non-smoking household.
