One more question: is there such a thing as a conductive lacquer that
would stop or at least significantly slow down any future oxidation of
the brass?

Yup, nickel plating. It helps a lot.

The oxidation isn't actually as much of a problem as it seems, because
the plugs are designed to scrape it off of the tip and ring contacts when
you plug and unplug them. They are self-cleaning. I think that the Gray
Switchboard Company actually held a patent on the long-frame design around
1900 or so.
