Can someone help me identify this Edelbrock Intake?

[vdubn]

I bought this from a gentleman, and it says Performer 5.0L on the manifold. I have seen this exact style in a couple of pics, but not many.

Someone mentioned that since it has 5.0L inscribed on the top, it may have been a limited production Edlebrock intake that Ford had them made, like a Cobra or something.

I don't think it was anything real special, but just trying to see if someone knows exactly what it might be? I thought maybe it was a counterfeit, since it has the "5.0" on the top, but it also has the actual part numbers on the upper and lower manifolds as well.

Thanks in advance
