Where did these carbs come from ?????

Long story short - but these 8 carbs, log manifold and air cleaners came from my brothers 20 year old junk box. He cannot remember where the came from.  I have looked at many kits but I havent found where they come from either.

CAN ANYBODY HELP !!!!!!    I like them so much I would love to have some more.  I think they would look great on some more Rat style cars.
