Steam Engine Demonstration Model

This model shows the internal structure and operating principles of a working steam engine. The metal cylinder is cross-section cut and is covered with a clear plate to show movement of the piston inside the cylinder. Complete with working parts i.e. the piston and slide valve both move and the link motion and reversing method can be observed. The movement of the wheel is light enough to demonstrate even by blowing air from one's mouth. Dimensions of model on base are 14 x 7 x 4 inches.
