What would you call this neck construction?

Check it out, you can order zebra and reverse zebra for “neck” and “bridge”, but not “set”. Also it says Trembuckers are temporarily unavailable. It might be an odd website thing.

Ah. I see that now. Same with the Whole Lotta's.

BC Rich had marketed something similar recently as their new technology, they called it "Invisibolt"...

" In 2006, they introduced the IT (Invisibolt Technology) series, which combines elements of bolt-on and neck-through designs: The neck is bolted inside the body to make the guitar look much like a "neck-through", but the neck joint is still visible."

Interesting. Although on this one, the neck is definitely glued in. If I took that bolt out, I still couldn't remove the neck.
