The model is very large and heavy, measuring 16" at the base, 11" high, and 9 wide overall. It is constructed of brass, stainless steel, aluminum, and what looks to be mahogany wood. I have never run the model but presume it does work. The beam moves freely when the flywheel is turned.Look closely at the photos and ask me any questions you have.
