Offenhauser intake I.D. help needed.

Need help with an I.D. on this Offenhauser intake that I just picked up. It seems to be an early one, but I cannot find any that are quite like it.
It is not a "dual port", and the "c series" that I see do not have the 4 individual holes, but an open plenum from the carb mount.
The only markings on it are "360" and of course the "Offenhauser" insignia.
it is a split runner system. The "engine side" two holes are divided from the "outside" two holes, and the "wall" ends right in the center of the runners going to the second from the end cylinders (cyl # 2 and 5)
Anyone seen one before?

I got some clarity on this particular intake on a Facebook page dedicated to the ford 240/300. The current owner of Offenhauser got on and gave some great insight, and I figured I would share it here in case anyone comes across the same thing, it may help them. Paraphrased from the FB post by the Offenhauser CEO:

"This intake predates the C series, ultimately what is now the C series match plate used to be the Equaflow, when Offy introduced the Dual Port they decided to retire the equaflow and make it into the Competition. The intake you have is the original 240/300 offy intake part number 5886. This wood pattern was used to make all of them"

I thought that was a really cool piece when I saw it on the Facebook page.
I'd hang onto that even if I didn't use it.

Is it me or does it look like it's been welded (pic #3)?

And, if you look at the same pic, it appears as if the carb mounting surface is tilted slightly forward, towards the radiator.

Cool as hell tho. I like that the CEO responded and showed a pic of the original wood pattern.

It has been welded/repaired where the stock exhaust manifold mounts for intake manifold heat. I will have to test it to see if it seals in order to use a heat plate that runs coolant through it. This was disclosed by the seller before I bought it.

Also, the carb surface is tilted on all of these. The engine is tilted back, and this angle makes the carb sit level when installed.
