The hanging skeleton is part of these guy's collection of medical junk, probably one of the few things that anyone would want along those lines. He also has a number of quack medical machines at very unrealistic prices. I think he was watching that show "Oddities" on the Discovery channel and thought he would take a crack at it, except that he is in a Podunk area called Errington that isn't even really a town, not a big city like New York. In fact it's not even really on the way to anywhere else, you have to go out of your way to get to it. Even in the case of the shop featured on that show they know they have a limited market and that only the really rare and unusual stuff is what people want, not stuff like incubators from the '70s.
