Hehe, thanks. I forgot to mention that this one is strictly a wall hanger. I have a spare frame in rough condition that, at some point, I'll restore and ride. This one I'd like to leave as is, except for maybe doing a light, careful cleaning of it. With respect to the chain, I'd like to clean some of the gunk off of it and just leave it draped over the cogs and chainwheel. I don't want to damage them by using the chain, but the chain itself really won't be seeing any use. My biggest worry is the rust. As Neil Young says, "rust never sleeps." I believe him.
