Thanks y'all for the info!!

As a Machinist for the past 35+ yrs but now retired, I can easily re-establish the lanyard hole (pin is still in place) and also have connections with a plating facility to strip.
Maybe if stripping results are satisfactory, possibly then cerakote finish to a flat black.
I feel I'd at least like return this piece back to some form of respectability.
Obviously, I don't consider this as an investment.
