Ernst Plank Toy Steam Engine

Description (Brief)
This toy steam engine was manufactured by the Ernst Plank Company of Nuremburg, Germany during the early 20th century. There is a small metal plate on the toy’s wooden base that reads “Hercules,” possibly the model name of this engine. The toy has a pressed metal firebox below the boiler. The boiler powers a vertical slide valve engine shafted to a flywheel, with a flyball governor.
Ernst Plank founded his company in Nuremburg, Germany in 1866. The company was well known for manufacturing a variety of metal toys like steam locomotives, stationary steam engines, early photography equipment, and magic lanterns until its dissolution in 1935.
