Whoa. That's weird. Looks like one of 'em Anniversary SRs without the PG. But that's not possible - the "PG" is part of the body, no? Weird, nonetheless.
I think Dr. Frankenstein thought the maple top was so cool that he wanted to show it off (not unlike the les pauls without the pgs). Then he exchanged the neck for a rosewood neck (unless they made a rosewood neck).
