No mate, I've never had Mark Brights shirt in my collection, but I know the story.
He gave his FA cup final spare to a woman who then sold it on to a collector, who then sold it on to another collector. It then ended up on ebay and Mark got wind of it, and obviously wasn't too chuffed about it. The guy who was selling it got some stick, but had bought it in good faith and had actually done nothing wrong.
