Period correct for your old hot rod or custom with Oldsmobile Fiesta hubcaps Starfire dog beaters flippers whatever you want to call them the ones with the 3 spoke spinner mounted in the middle. Dont know who made these Cal Custom maybe notice the reliefs on the back for them to mesh with the spokes. Drill a hole in the center of the cap and screw them on. They have w nice patina to the chrome with some minor flaws but still a good shine. So they are driver quality. Only set I've ever seen. $100 shipped.
