[GreenKeys] Recommended lubricants for Model 33

[Jones, Douglas W]

I have Teletype maintenance manuals for the Model 33 from the
1960s (manuals that came with the TTY I have), but I'm wondering.
Lubricating oils have come a long way from the time those manuals
were printed.  Synthetics that never leave behind any gums much
evaporation there has been would be particularly nice.

What brings this to mind is the fact that many of the lubricants
in the old mechanism turned to gum in the years between then and
now.  Degumming things involved, in many cases, complete disassembly,
and in other cases, Q-tips and wipedowns with things like WD-40
and Goo-gone.  Now that things are pretty nearly gum-free, the
question is, what to use to re-lubricate that minimizes the
likelihood of gummy stuff over the next 50 years.

The manual mentions the following lubricants
-- KS7470 oil
-- KS7471 grease
-- 108805 grease

(and what's that about something without a KS number, I thought
everything in the world had KS numbers, at least if it was used
in maintenance of anything built by an AT&T subsidiary.)

So, what are the modern equivalents of these lubricants?
