Hi Jcp,
Thanks for your reply!
My center cap is original with center hole for security screw ( I have posted photoshop image without hole because this part of the art is scratched by screw )
I have removed this cap about 10/12 years ago from original Sega Super Monaco GP Cab, but is different from your Power Drift one because this cab was made by Sega Europe LTD, not by Sega Enterprises Japan.
At Videogameparts this one is marked as NOS not as reproduction.
