Howdy, boys: You know the kind of "dry-type" air cleaner that was used from 1937 to 1940, or '41? Well, I have noticed that there are two types of filter element designs; there is one that looks like common hardware cloth with square holes in it. The other is a sort of "honey-comb" design. Are the differences year specific? For example, is the square type for the early years? Is the honey-comb type for later years? Or, is it just the opposite? I'd like to know what is correct for a 1939, if someone knows. After 70+ years there seems to be no way to tell from the cars I have looked at. Thank you, all. Much obliged. Mike

Different suppliers, slightly different designs. The Oakes, Industrial Wire Cloth Products, and Burgess Battery designs had the filter element held between two zinc plated square weave metal screens (hardware cloth). The AC design was part number 91A 9600 A1. Stamped into the bottom was “91A 9600”, “Made in U.S.A.”, “AC”, and “Pat pending”. Differing from the other designs, its filter element was held between two raven black screens having staggered round holes. The Oakes design had its part number, 91A 9600 A2, stamped into the bottom as well as “OP”. The Industrial Wire Cloth Products design was nearly identical to the Oakes design. The difference consisted of the part number, 91A 9600 A3, stamped into the bottom. The Burgess Battery design had its part number, 78 9600 A, stamped into the bottom as well as “PAT. APP’D FOR U.S. AND OTHER COUNTRIES”.

Great detail, mike! For a restoration tip, the Copper Choreball still available at groceries and hardware stores is perfect for the filter material. There is a single light spotweld holding it together, carefully break that spotweld and open it up flat, then fold it to fit within the canister. Remove it for oiling, then reinstall it.
