Origin of "Arkansas elevation" in aiming gunnery or rifles?

[pauamma]

With some digging, I was able to trace the origin of "Tennessee windage" and "Kentucky windage" to the early rifles of the same names. However, I'm unable to find a similar origin for "Arkansas elevation". DuckDuckGo (correctly but uselessly in this case) points me to contour maps and GIS products for Arkansas. Does anyone know?

I tried "rifle Arkansas elevation" and got a bunch of links related to the AR-15. :)

So did I - together with one to a brand/model/whatever called Elevation. :-) Still no closer to an answer, though.
