Believe they are Lincoln, at least that's what the guy I sold them to said they were. Difference between those and Ford is the Lincoln has no provision for holding on small hub cap, in other words no "***s" around hubcap opening, or clips.
I have purchased 2 pairs from 2 different sellers and on both occasions they were marked up as 53 F1 and when blasted they were both marked up 53 Kev
