O riginal nothing replaced. 1950s Minneapolis Moline tractor clock made by Westclox This one is all original and works. I tested it and the second hand works great and keeps time with a digital clock. Motor needs a little oil. And should be rewired. I cleaned it up some on the chrome, but could some more cleaning.
