Technical Question on Hub Caps 1953

I'm attempting to build a replica of the 1953 So Cal '53 F-100 Hauler and the Double Trouble '34 Salt Flats racer. I need to know if anyone can tell me the type of hub caps, which were used on the F-100 in these photos. Any help would be greatly appreciated and would help me build an more accurate model. Thanks.

 

Look like '54 Cadillac on the big photo, which looks like it's from a recent concours car show (Don't think they're available in scale.)
The old HR cover is too small to really tell but looks it might be a Ford from '40s or early '50s.

 

hard to tell from pic could also be 56 buick they were popular swap also.

 

Sure looks like it. You guys are awesome!
