Keyton Roberts Tunings

[Joe Delaronde]

In the tunings section I can't find Keyton Roberts tunings.
What are his tunings, starting from the 1st string, smallest, to the bass strings.

What is the norm for listing tunings, smallest to largest strings or visa versa?

I learned it as small to large, some formites list them backwards (??)
Is Keyton's steel a 22 1/2" scale?
