Got these on a bike and can't work out what's going on with the crown on them

I've taken the crown off them and this is what's left

There's some kind of second race that was visible on the bike because it sat below the other!
But it looks like(if I ever managed to get it off) there's two different diameter steps to fit 2 different crowns onto
