Burrell Overlook Estate Pelton Power Plant Little Falls, New York, USA
We believe this was originally installed in about 1889
You can see the whole mansion at http://www.burrelloverlookmansion.com Check out the interior photos, then click on the picture of the Pelton Wheel.
This is one of the earlier wheels made by the Pelton Water Wheel Company.
The patent date is 1880, what a wonderful old wheel.
