Steering Wheel Question

When I bought my 72 Duster it surprisingly came with the exact steering wheel I wanted. I first thought it was a Grant Classic Gt wooden steering wheel like the one pictured below cause it is exactly the same in appearence.

But today I took it off of my steering colum because it was was just standing on my garage floor and I didn't want it to get ruined. Upon inspection of the wheel I noticed it doesn't say "Grant" on it anywhere.

At the top of the front hub of the wheel it says, (The "500") and at the botom front it says "Superior Perfomance Products" with a small stamping of a guy flying threw the air wearing a helmet and holding a steering wheel.

Sorry I know this was a little long of a post but curiosity got me and thought maybe someone could shed some light on what company made this version of this wheel.

Thanx.
