You can see it's location in this image. You can't read it in this one but it's on "ALL"!!! There's various information on the "back-sides" depending on size and color.
there are 8.5 wide (56mm) (silver and black), 9.5 wide (56mm) (silver & black), 11" (36mm silver) & (50mm black)

The JWL is a "Japanese Wheel Standard" logo that is found on the GM original wheels and no other aftermarket replica wheels.
Every wheel manufactured in Japan has to meet the JWL standard. Everyone!
Enkei has NOTHING to do with the ZR-1/A-mold wheel.

The question was how to identify what is commonly called/known as a ZR-1 wheel which I've always been led to believe is the 5 spoke/A mold on the '94 - '95MY ZR-1, the '96MY GS and CE only. Is that correct?

And they're called "saw-blades" not "ZR-1" wheels! Every model year of the C4 shared wheel style among base Corvettes and ZR-1 Corvettes until '94!
Is there something I've missed here?
Regardless the "saw-blade" wheel you reference also bears the JWL identifier. All C4 production wheels '91MY + bear the JWL identifier.

Yes there's production information on all the GM wheels. The easiest identifier is a JWL" casting on the outside painted surface centered in the second window clock-wise from the valve stem.
You can see it's location in this image. You can't read it in this one but it's on "ALL"!!! There's various information on the "back-sides" depending on size and color.
there are 8.5 wide (56mm) (silver and black), 9.5 wide (56mm) (silver & black), 11" (36mm silver) & (50mm black)

NOT Corvette wheels ! And you didn't need to remove them and try to get through all the brake dust to find information that would have confirmed they weren't Corvette wheels anyway! Your hands are still clean!

My mistake
I was working on a wheel off a factory ZR1 being a ZR1 wheel ;taking into account the unique 11" rear with 38mm offset
that only fits ( correctly ) a ZR1 regardless of style

I said they weren't Corvette wheels. I said they were Camaro SS wheels.
I didn't get through any brake dust. The "GM" letters are cast on the front the same as the "JWL" letters are on the ones you pictured.
Yes my hands are still clean, but what is your point?
