Help Identify Early 318 Single Plane Intake

Thanks everyone for answering my questions, and coming up with the answers I was looking for.

Enjoyed learing more history of these parts and even some racing aspects they were used for. Looks like there are still a lot of these single plane 2 bbl intake manifolds on the road yet today.

Actually like the low profile balanced look of them, makes a nice looking engine bay component.

Thanks Again !!
