Help Appreciated!!

Friend of mine Was a old Mopar Dealer and has been selling his old parts on Ebay. He found a intake manifold that he is having trouble
finding what it is for. It has the # 3698 442 AE on it by the firing order and in front of the carb morun 10 15 73 any help appreciated.
We think it might have been part of a police package due to it's a quadrajet mount. whitch would have been a cheep replacement carb for squad cars.
