Yall have seen long interval oil changes, but have you ever seen a factory filter from 1964?

383 I’m working on. That’s the late 50s/early 60s AC logo, and as you can see the oil in the pan wasn’t the greatest. No marks on the bearing shell and the sump looks like it came out of a bog, but the crank looks like it just rolled off the production line so far so that’s pretty neat.
