Oil filters were standard on the prewar 356 engine because of the hydraulic lifters but optional on the standard eight and sixes. In 40 Packard went thru a lot of experimenting in filter design and flow on the 356 to solve intermittent noisy lifter problems but by early 41 I believe they had settled on a filter design. The filter element and canister were then the same for all engines but flow on a standard eight and six was different because those engines had solid lifters. Different accessory numbers for the factory kits are due to the steel tubing lines and fittings being different depending on engine.

I expect a Packard prewar filter assy could be found without too much difficulty and postwars are readily available but you would probably need to fabricate your own steel lines. There were also a lot of aftermarket filters available at the time but those generally had rubber hoses and the canisters varied in design and color. Prewar factory canisters look somewhat similar to postwar but as I recall the bottom is slightly more deep and pointed in prewar canisters. Prewar filters had the inlet on the bottom and exit on the side while postwar filters were just the opposite. A postwar filter will fit and work but using one just depends on how authentic you would want to be with the tubing.
