52's were equipped from the factory with small hubcaps that attached to those clips. 1/2 ton were small overall than 3/4 ton. due to shortage of stainless steel they were made of metal, painted gray with block letter chevrolet stamped in them. lettering was painted black. baby moons, large or small, where not a factory item. i found that steel hubcaps to be one of the hardest to find items and when one is found it is usually rusted through on the portion closest to the ground where rain water had splashed onto continually.
