Yes, it's a Purolator L-8 oil filter. However, the 1934 Eights & Super Eights (not sure about the Twelves) used the Purolater L-6 which was almost identical but rather than the end bosses with the inlet/outlet and threaded holes for a mounting plate, the L-6 just had a NPT threaded inlet and outlet. By making (or buying) adapters you can use an L-8 in an L-6 application. They are both full-flow filters and as 1933 didn't have the full-flow system, I don't think the L-6/L-8 series dates back to 1933, at least for Packard.

EDIT: I know it's a bit off the topic, but thought I'd add a warning here. NOS L-6 and L-8 filters were not that easy to find, even 30 years ago, so many of us bought newly manufactured units from Bob Turnquist and these were satisfactory tho expensive. But every so often I see an NOS one appear on eBay and hope the buyer never uses it (or an equally vintage cartridge filter) as I've seen several cases where the filter internal paper media and adhesives, though "new", were so deteriorated that the hot oil and pressure turned them into paper paste which in turn choked oil passages, pump inlet screens, etc., and you can imagine the consequences. In these cases the filters may have been stored in a less-than-ideal environment, but I sure wouldn't want to take a chance on one.
