1ntCobra,
I have seen (and crawled all over those cars) at Bill Murry's shop. He was very kind to let us take a million photos. We even have some close up shots--somewhere...not sure where, however.
Those scoops could very well have been made by the AC factory. I frankly don't know. My "original" comment was referring to the "1st" race cars they build, not so much original as in terms of "what is right, or correct." If you look very closely at those scoops, they are actually not very much like a 427 scoop. They are more of a bent "U" shaped piece of aluminum that was just "stuck on" the hole because the needed a bigger scoop. Every car was different in different ways and every car evolved over time as it was raced. "Originality" had little meaning to them back then.
