In the late forties and early fifties all car lube oil filtration were low flow bypass.

"Full flow" cartridge filters came later. They probably sold them on fear that some bit if dirt would sooner or later get to a bearing and ruin the engine. I was there in the early 50's and never heard of that happening. Perhaps we'd be fine w only by-pass?? Kinda like selling high tech anchors via the fear of winding up on the beach/rocks.

But smitty's employing both is the "cat's meoww".
