This is a vintage salesman sample cast iron automatic type cow watering bowl . The entire unit measures 6” X 5” X 5”. It has a spring loaded center piece that is intended to turn on the water when the cow pushes it with its nose. The spring mechanism works but this is a non-functional model. It looks just like the real thing.
The bowl also has indents on both sides that appear to make the model double as a desktop ashtray.
