I received the below picture of a Ford document dated November 8,1956 that states 'very shortly, new 1957 FORD cars and trucks will have, production installed, a brand new disposable oil filter'.  Most likely Ford made the changeover over a period of time, after this date, as Ford used up supplies of canisters.  Which is why cars produced in January could have the canister installed.  I have been using the Dearborn Phase I prototype pictures from December 1956 for the standard for my engine which has the canister installed.
