I think that the answer to the first question may be yes and no to the second. I own two 1928 Model A’s, both purchased in 1989. I bought the first one at the Pate Swap Meet in Texas (March ‘28 open cab pickup). This pickup has all the early features including the AR wheels. I bought the second (May ‘28 roadster) from a private owner. This car was in barely running condition when I bought it and has the later 1928 features. I spent about three years making both road ready.
Around 15 years ago, at a motel on a Model A tour, three Model A “experts” noticed that three of the wheels on the roadster were the AR type. Even though I had painted these wheels and changed the tires several times, I never noticed this.
I know that this has been controversial, but it has worked for me all these years.
