I bought this clock 3 weeks ago at a moving sale for $40. It was a real mess when I bought it. It wasn't running and it was full of varnished grease and grime. I think it was sitting in the kitchen next to the range. I brought it in to my watch/clock guy and he charged me $160 to clean/repair it. He said it was one of the filthiest pieces he's ever worked on, but it cleaned up beautifully. I think it's pretty rare and worth around $500, but I probably won't sell it. Also, i'm glad I rescued it and got it running again.
