    That's good stuff.
    Any chance of showing the innards?
    It's got to be mercury right?
    And it can do 220v switching?

    Frank, I would have been sure you would have ran in to older ones especially being on the east side.

    My fav. I want to open a restaurant and hang all this stuff on the wall. Need a name though. Maybe call it the Superheat taveran or the Hartfood loop Bar.
