I Was browsing Ebay and came across this, looks like it will fetch a few bucks. Nice example.

While it's neat that you can purchase them, it's sort of a shame that the patent office sold off the patent models.

Cool, it went for some big bucks. I tried to save the auction as a web archive but that option is greyed out for me on safari. It would be nice to have on the site somehow.
