Nope. Cowboys wouldn't know what to do with such a thing. Hell, I won't even touch it and I'm far from a cowboy.
In case you're interested, here are some pictures of other guitars from the same guy's collection. Two are "conventional" 7-strings and two are 5 classical string/3 (fretted) bass string hybrids, one with fan frets. There's also a link to "under construction" pics of the previously mentioned Rob Allen instrument on the same page.
