Re: Walnut as a solid body tonewood...
Those are cool guitars. Actually, it was just 'The Paul', right? There was actually a model called 'The Les Paul' that was the most fancy LP that Gibson made at the time ('78?). I know Steve Howe used one. As far as a pickup for the walnut one, I'd probably wait to hear it first to see if there is anything you need to 'correct' with it.
Oh, and here is a rather affordable Reverb listing for 'The Les Paul'.
