Can You Help Me ID These Cragar Wheels So I Can Sell Them?

4.5 and 4.75 would be dual pattern.
I've got Western turbines on my D100 that are 4.5/4.75 dual pattern.
On 4.5, they are tight to the inside radius.
On 4.75, they are tight to the outside radius.
They don't fit any other pattern.
Round hole washer is all that's really needed.

4.5, 4.75, and 5 would be uni.
4.75 is not tight to either radius.
I have several Keystones like this.
Correct, oval washer is needed for intermediate patterns.
These are the most problematic.

4, 4.5 and 4.75 would be uni.
4.5 is not tight to either radius.
Not sure I've ever seen this personally, but I've heard of 4" uni-lug patterns.
