Upon this page one will find a list of those hot shot furnaces which still exist on this planet...the masonry ones, at least. There appear to be plenty of those iron British Addison furnaces sprinkled about in museums, and we're not going to attempt to track all of those things down, worthy though they may be. This list is intended to be as complete as possible, so if you know of a masonry hot shot furnace not on this list, the existence of which can in some way be made evident, I would very much appreciate your letting me know, perhaps through this site's contact page.
