[GreenKeys] KS7470 oil

[Don Robert House]

Very nice work Doug,
Thank you for sharing.  Please let us know if you can find anything
for the Western Electric KS7471 Grease which is also needed for  
lubrication of Teletype machines.
I have a tube of it here, but finding it on the web would be easier  
than sending the tube to a chemist.

Best regards,
Don

P.S. In case you do not know the KS means Kearny Specification after  
Kearny, New Jersey where the WECo Specs were written.

Climbing around on the web, I have found the specs for KS7470 oil,
and I have found the specs for a number of other oils with which
to compare it.

The results of my exploration are here
-- http://www.cs.uiowa.edu/~jones/pdp8/UI-8/ks7470oil.shtml

In conclusion, Starrett 1620 Tool and Instrument oil is almost
certainly the exact same thing.  $6.94 per 4oz. bottle

Several other highly refined white mineral oils are every close
matches.  Lubriplate FMO-AW 200, for example, is available for
about $139 for 5 gallons or $1,466.38 for a 55 gallon drum.
bulk discounts are nice, but I don't need that much.
