I get the gut feeling that this machine was not likely to have ever been subject to over-stress abuse. Closely held. Too precious to its few minders.
Fair chance that ALL of those workholders can "come good" if carefully cleaned up.
Surprised to not see even one 4-Jaw independent in the mix, but those are not expensve in small sizes @ low RPM ratings.
I guess for this the cathead was used. At some point if i have a use for it I will get a small one.
