I approached a nearby antique dealer on Wis Hwy 16 between Portage and Wisconsin Dells to act on my behalf and he obtained all three Wig Wags.  I bought the best of the three for $160 and restored it completely.  I have added crossbucks and a "2 Tracks" sign to it (both old with 'marbles').

It is fully operational in our side yard.  I have a bell, too, but just connect it to the DC power source by alligator clips so the Wig Wag can run silent as a favor to the neighbors.

I have seen another "private" Wig Wag along the old C&NW tracks north of Madison, Wisconsin, and a whole yard full of signals along US Hwy 12 near Niles, Michigan.  I stopped and introduced myself to the fellow there and he immediately sought out one of the other Wig Wags from the antique dealer here in Wisconsin."
