Servo Style Milling Machine Power Feed From The Great Big Electric Company

This unit has been on the shelf for years marked “dead” I don’t know what the issue is or why it is not working just that at one point it was opened and looked at. There is also a brand or model skyey near the model and serial number. I do not have the original bolts for the outer case. There is also a missing plastic cover for over the bottom. (I was told they get knocked off by carts all the time).
