I actually restored mine years ago. See pictures in this thread:

Though with the prices so low you could find a set for sure. I still have a set for sale. I was in the process of selling them last year but the price to ship was crazy. Now it's time to find someone local to sell them to. Better than sitting in my basement not being enjoyed.
