Needed: 64 valiant dog dish hubcap expert

Hi Guys
Restoring a 64 V100 Valiant and was wondering if anyone can tell me if the dog dish hubcaps on these cars were painted or plain. The paint I'm referring to is red blue and black in the center and the indentations. I have seen them for sale as new old stock or never installed both ways and have seen photos of restored cars with painted caps and survivors that were unpainted. The caps that came on this car appear to have been unpainted (unless the paint just wore off over time). Anybody know anything about em?
Thanks
