Hot Rods Wheel Center Caps

Can anyone tell me if anyone is making this style of wheel center cap anymore?
I have seen in them in recent magazines but no mention of the provider.

 

I have seen those on a number of cars over the years, and I believe they were "home"made.

American Rebel wheels sells them. I want a set for my wheels on my 51

IIRC Real Rodder Wheels has them, possibly Team 3 also.
