This followed me home today. Looks to be a keyway milling machine. After taking pics I gave it a good dose of kroil oil as most parts are froze up. I'll leave it set a few days and when I have time I'll try to get it apart. It may actually be worth fixing up and putting a motor to it and see if it will work. Has anyone ever seen one of these? This is the first one of these I have ever seen.
