Yeah, I've purchased a few items from him in the past, and he did tell me that the PRS bridges he's selling have the newer Gibson-style saddles and not the ones that are shown in the image. I did find this one on Reverb, though:
USA PRS Paul Reed Smith Core McCarty 594 Bridge, Tail Piece & Studs (for Tailpiece only)Condition: Very Good/Excellent (light play wear, works amazing! Includes only the parts pictured)

I don't think I really care to spend that kind of money for a tonal experiment, though. It would be ideal to find a set of individual saddles, but they don't seem to be available, either.
