its a reproduction of the 2 four bbl air cleaner made with a base to fit a single 4.
i have one too, K&N makes an element....# C207AB
there's a flat piece of steel missing it has a hole in center to attach to the carb stud in the airhorn, and two studs to tighten the air cleaner down. i will look to see if i have the bracket, i'll make a drawing of it
