To those comments about "this thing should be in a museum", it is. The Roots of Motive Power is a working and restoring museum in Willits, Ca. Comprised of a group of people who have over many years put together a pretty big stable of steam operated logging and construction equipment (as well as some gas and diesel antique stuff) that has been salvaged after years of abandonment in the woods, or as they explained at one their shows, this shovel last worked on the San Francisco Oakland Bay Bridge and was left in the mud flats for years (at least that's what I think they said, don't quote though LOL). They do their own restoration work and used to put on classes where you could join up, and learn all about these machines and do hands on work. They generally have a big show once a year, used to be on Labor Day weekend I think. Anyway, if you have interest in this stuff you really need to go to their show.
