I can answer that.
This guitar was built for my friend Tom. I bought it years ago from him, and I resold it quite a few years ago. It had 2 bolt-on (CE) necks.
Why 2 necks? As I recall, Tom wanted a Gibson ‘50’s sized neck, but the original one received was more like a PRS wide fat. So, PRS made him a second fatter neck. Since yours does not meet the specs on the certificate, you evidently have the later fatter one. I also recall that the original neck was unfigured rock maple, and PRS acquired a flame blank for the 2nd neck (PRS used to stock no flame maple blanks in the vault),
The first time I saw this relisted after it left my hands, it was listed with only one neck. While you got a great guitar at a nice price, it’s too bad that someone decided to split the necks up. It’s still unique as a CE PS, but it was even more so as the only one I know of that was made with 2 different necks.
As a side note, my friend Tom was an interesting player/collector. He had serious back issues, so guitar weight was a big deal to him. He required a light Les Paul, and so, the original “cloud 9” Les Paul, under 8 lbs, was developed for him (through Wildwood).
