Thank goodness; before he passed away, Bill Stokoe had his entire backyard (and some of the front yard, too) filled with signals and related appliances, all restored, hooked up to electricity, and fully operational. He would flip a few switches, and the whole thing would come alive. About ten years ago, I was very fortunate to spend an afternoon at his home. I've been wondering what became of his collection, and I'm glad to hear it's being preserved.
