I wouldn't know a bloody thing about old Ingersoll compressors in Western Canada, Adolph, or Adalwolf, or WTF your handle is today.
Not me,....
question: What's a "Millwright," anyway ?

I Googled that question a while back and a Millwright is a guy who installs machinery in a plant and makes sure it's level and ready to rock & roll. At least that's what I got from the explanation.
