This engine is similar to stirling engines that were made in the early 1900's. The design was used in factories to run machines. The engine is constructed of a brass heat exchanger, stainless steel pistons and cylinders; the rest of the engine is made from iron castings. The flywheel is equipped with a pulley to run accessories. The engine is hand painted and has an alcohol burner that operates the model for 40-60 minutes.
