Perhaps this is also the FIRST example of such an intake (side by side 2X4). Makes me wonder now what the source was for Shelbys twin paxton setup in 1965 or 1966. Where did HE get his manifold?

The Shelby twin Paxton (actually McCullogh) used an Edelbrock 2x4 crossram.
Mickey Thompson produced 2x4 crossrams for any number of engines including the FE, BBC, Pontiac...

The Edelbrock crossram allowed the use of the stock (or at least a regularly driven) distributor. The M/T crossram for the FE required the distributor's drive be extended, with a spliced in piece. This led to some spark issues at higher rpm's when using the M/T manifold with a distributor.

Ernie, the keyword in my post is appears. I can't find a quality picture of the crossram used on the Paxton Cobras, but you can make out the runners on this one, while under restoration:


The crossram was the first intake to make one hp per cubic in. on Edelbrock's dyno in the late '50s, on a smallblock Chevy such as this one:


The intake on the Cobra appears quite similar to the one on the Thunderbolt you posted; you may have to enlarge the image.

Here is the custom SOHC Weber manifold built for my cammer car by Hogan's Manifolds in CA and being finished by Inglese Inductions in CT:

Well, after much consideration I believe I have decided to bore and stroke my engine to somewhere near 520ci, and I believe I am going to have hogans make me a 2x4 intake. I wanted a SOHC, but the engine alone is around $35,000. A bit too pricey for me.
