Oil filters I believe were an option. I had a 49 packard std with no filter.

A filter was always standard equipment on the 356 engines from 1940 thru 1950, optional on the others, and this was because the 356 used hydraulic lifters. Full flow filters on Packard ended in 1939 with the last of the Twelves and Super Eights - these engines were all full-flow beginning in 1934 and perhaps on the Twelve back to 1932.

A modern spin-on filter in bypass mode offers no advantages over the standard Packard canister type bypass filter other than a little less housekeeping when changing elements. With the limited use and good maintenance (oil changes annually regardless of miles, for example) that collector cars usually get, it'd doubtful that a filter adds very significantly to engine life, at least over the engine lifespan that most of us will experience with these cars.
