You left out the amusing part : Some car makers claimed that filtering the
oil was unnecessary!

My first car (a 62 Chevy) had the optional, bypass oil filter canister
mounted on a bracket, with external lines to an oil gallery and the side of
the crankcase.  Oddly enough, Triumph had already been using full-flow
filters for 6 or 7 years (and my Chevy also had the rope rear main seal),
showing again that they were actually innovative cars for their time.

Shame they couldn't keep it up.
