[GreenKeys] modifications

[Jim Haynes]

Well of course it is yours to do with as you please, but...
Ideally we could find you one that is more like what you want, and
then you could preserve that one as an artifact, since it is now
four-or-less of a kind.  (Tho there must have been an awful lot more
of them at some time in the past, but presumably they are all gone.)

How did you get the blue paint off without destroying the gray-green?

I have a friend who has one of the W.U. 100-series machines painted
yellow and orange tractor colors.  He happens to be color blind, hi.
