Jim Carter most likely has a variety of used oil bath air cleaners and could match the air cleaner to the year of a standard carburetor.
JC sells a very nice reproduction
1950-1959 "spark arrestor"-style air cleaner with a paper element.
This style of carburetor was standard on light trucks for many years (it clamps on the carburetor; you'd have to remove the center post on later Rochester air cleaners - 1960 and later, I think).
JC also sells a very nice original-style oil-wetted replacement element for that air cleaner (works over many years)
1936-1940 and
1941-1955st.
