There's a photo of jazz guitarist Randy Johnston and his Starfire IV in a copy of Guild Gallery I have. So I checked out his web site, and there's a link to see a video of him playing what certainly looks like a Starfire IV. Not the greatest quality, but pretty cool. He sure gets some jazz tones out of it!
