There have been a few tongue in cheek answers, but nobody
gave the real one, so...

Tree made a few milling machines, somwhat similar to the Bridgeport
design. Apparently, from the above info, they also made one a bit bigger
than a Bridgeport Series II. Some people feel that a Tree is far superior
to a Bridgeport. I think they may have box ways, not dovetail. I have
only seen one or two, and not the bigger ones.
