My 1982 Case MB4-94 uses old style metal cartridge filters. They were common in the 50s-60s.
I've had a few older pieces of equipment use that style too.
Have done tractors that is was just like a big cloth "wick". Pretty much the cartridge but with the metal cartridge contain it.
Sometimes these are bypass filters too, full flow filtration wasn't the standard till maybe the 70s?
Bypass was an improvement over no filter.
Which sounds odd, but tons of engines built nowadays have no oil filtration. Usually under maybe 10-15hp.
