Classic Smoking - listen carefully to the crackling sound of this firefighter. It reminds you of the old Tractors from the last century. It uses water evaporation cooling. The alcohol burner is highly adjustable to control the speed. Enjoy the amazing sound and let the pleasing design fascinate you. Larger and more impressive than the rest. This very well made German Stirling runs using the supplied burner. Just add methylated spirits (denatured alcohol), light and place under the engine. Wait a short while for engine to heat up and give the flywheel a flick. It will burst into life and get up to an impressive speed. You can then throttle the speed by sliding back the burner or removing. Product is supplied assembled.
