Sounds like that is remanfactured to me. Also you said "this machine" then you said 1000 machines. I would suggest since you are replacing so much already just change to cord to a GFI cord and protect yourself and others.
sorry, wasn't meant to confused anyone..yes it'a lot of machines
Yes, i am proposing for the GFCI retrofit as well part of the proposal but I am just doing my due diligent to make sure I have some documentation to backup my assessment. That's all!
