can someone identify this wheel?

my 83 C10 had them from the factory and it was in fact off white, looked better than the glaring white of the aftermarket wagon wheels, and also had the more rounded edges to the holes. I never had the trim rings though, they were lost long before I got it. They were 8 inches wide, and I remember the woman I got it from used to buy tires from Western Auto. They went by the book which listed a 205 tire for the stock wheel which was narrower, and didn't take into account it had wider optional wheels. Needed at least a 235, I put 255s on it. So the 205 tires were way too narrow and looked terrible and wore out every year. She kept going back and they kept replacing them with the same size over and over. What a bunch of idiots. Thats part of the reason she hated the truck and I got it cheap
