Cast metal horse from a child’s toy?

Cast metal (maybe cast iron) horse This may be from an old toy. The horse is about 8” from front to back hooves. It weighs 1 pound, 3.5 ounces. There are holes on the sides of the body and head that may be where it was attached to the rest of the toy. I acquired this from an estate sale so I do not know the age, purpose or manufacturer.
