air cleaner with approx 4 1/2 throat opening

I have this nice looking air cleaner with approx 4 7/16" throat opening--- not sure if the old style 4 bbls were that size, just know it is larger than a 1 bbl by quite a bit.
Look at the pictures, the base has fram ka5 printed on it.
The base is a shade over 9" diameter
The top is slightly larger. with a height 3 1/4" tall
