Dog Dish hubcaps - are these original?

[jasonmiddlebrooks]

So these have been on my Dad's 70 c10 that I am restoring from the time I can remember. I don't think any came from the factory in white like this but figured I would ask if anyone knew if they did nor not. I am thinking about restoring them and finding some 16" 6 lug steelies to put them on. The stock 15" wheels will not work with the disc brake conversion I did up front.

Did these every come white from the factory?
If so what color was around the blue bowtie?

Anybody got a recommendation on where to buy new 16x8 6 lug steelies that would accept these dog dishes?

Thanks for any information
