I have a Ms Pacman cabinet that was converted to an Arkanoid and it still has the spinner on the CP. I'm not sure if this is an "original Arkanoid" spinner (if there is such a thing), but you're more than welcome to have it. I have no clue if it works.
I'm in South Carolina
I'll try to go by my storage this afternoon to snap a picture of it and remove it from the CP.
