Exactly! I did find the design but only on AV units rather than AR units. The AR ones exist but they seem to be almost as rare if not rarer than the AV ones.
I still wonder how they got the incuse so correct if it's fake, that's not usually easy to do. AFAIK it was definitely struck, not cast, but the almost perfect centering is also suspect since most of the genuine ones are at least slightly off center at the least.
