arandall: You have a 1952 Oliver 77. It is not a Super 77. Now for the 1952 model year I have seen both the original style fuel filter and the later style. The orignal filter can is held on with 4, 1/4 inch bolts. The most common one is the later one  that takes a 5/8 inch wrench to remove the bolt. The Fram number was : C1110PB back in the days when I changed them. I do not have the filter number (except for the Oliver part number) for the original filter element.
