Look
here and scroll down close to the bottom to Jerry Ward's Bass & Amp (note that the page copyright is 2002-2004).
He was the original bassist for Merle's Strangers and played on most or all of Merle's big hits of the mid and late 60s. Also wrote some for Bonnie Owens, IIRC a couple of songs for Merle too.
If I were interested I'd certainly want more photos, but my gut feeling is that it's real, although the finish looks either stripped or worn off. Price does seem high to me but I haven't checked 64 P prices lately.
