I have never seen a reproduction of this. That said, the one on my game is kinda faded, and I've had plenty of scratched ones off of games I've parted out. This seems like one Arcadeshop would have done years ago, but maybe there have been so many converted/parted that there's a glut of used ones?
Is there any interest in a Defender marquee project? A lot of them seem to be faded or flaky. And if memory serves, nice ones are demanding a pretty penny on eBay.
