Hot-Air Engine Toy

Usage conditions apply
Description (Brief)
This hot-air engine toy was manufactured by an unknown maker (possibly Ernst Plank) during the early 20th century. The engine is not a steam engine, as no water is heated. Instead the firebox heats air which expands and moves a piston to create useful mechanical work. The toy is a horizontal engine made of white metal with a 3.25-inch flywheel.
