They all look to be the new version. M+H never used holes in the center tube or covered the end with cellophane.
What it say where each one was made? Any text identifying Highline Warren on the filters?
Just because the one on the left (I can see it was make in S. Korea) has oval base plate holes doesn't automatically mean it was made by Purolator/Mann+Hummel. I doubt Mobil has any ties at all to Mann+Hummel after they contracted Highline Warren to take over supplying filters for them. And Highline Warren is shown as the company to take care of warranty claims for Mobil now (on Mobil's filter website), not Mann+Hummel like it showed before switch to Highline Warren.
