Induma milling machines?? I recently picked up an Induma milling machine, which I assume is a 1-S... Most of my research has suggested its an Italian Bridgeport J head clone, albeit a little beefier in some respects. I've never owned a Bridgeport, so I have no way to compare, but this one is pretty heavy.
