The first one (W&W #8 ?) looks like one I am looking at to rescue (if the price is right and I am lucky) I am always amazed at nice these machines "clean up" with a little TLC and a lot of patience. If the "works" weren't completely destroyed I would definitely go for it!
I just finished up one that looked way beyond repair but she turned out to be quite a little princess. Give it a try. If it don't work for you, send her along to me
