Parts of the frame a magnet will not stick to so it may be brass. The PAUSE AND REFRESH area has the lighted waterfalls that look like running water when lighted up. There is a motor with a wheel that makes it look like water running Everything seems to work on it but will need some minor repair. The bottom cover that you take off to change the bulbs has a couple of screws with the heads broken off and some screws are missing but that is about it.I did not want to do a bunch of work on it or cleaning as to hurt the original un-restored value.
