Fake Edelbrock intakes or Real with no Logo?

I have been looking for an Edelbrock B20 Blower intake for an Early Pontiac, I find 2 kinds, those with the traditional half moon Edelbrock logo and those without, it has occurred to me the ones without might be a knock-off?

I heard a Story from Don Iskenderian about the difficulty of getting Edelbrock to build one more hundred intakes for their blower package, I wonder if those last hundred intakes came without logos??

I guess if there is anybody who knows, he she will be here on the HAMB, I want to buy an intake, Edelbrock or Thompson, I don't want to buy a knock-off
