this is a beauty ring on one of 5 wheels/caps/rings I got from the 2nd owner of a very original '58 Chev 3100, and I'm fairly sure they were bought by the original owner from the dealer or aftermarket when he got the truck new .... that ring has very evil pointed spring fingers on the back that jam it on against the wheel, same as a full wheel cover, I've never seen any other way to hold trim rings on, paint be damned
the only picture that would indicate trim rings were "correct" on any truck would be a factory picture, particularly from an accessories brochure, and the only factory advert pics I've seen with other than the regular hubcaps had the full wheel covers same as the cars, I've never been able to find any GM reference in any accessories list or the master parts catalog for the rings or full caps having been offered for trucks - I'd be really doubtful there was a special beauty ring for Cameos only .... but there was a variety of them offered aftermarket back in the day
