WTB: Sega Saturn Battery Cover

So... long time no post, I know. However, I've just recently re-kindled my love for video game collecting after my buddy gave me a sizable chunk of his collection pro bono. Included in this haul was a Sega Saturn (a first for me), that seems to be in tip-top shape except for the battery cover on the back of the unit. Never having even seen a Saturn before, I initially assumed the worst as it looked like a big piece was missing, but apparently just the tiny battery goes back there... Anywho, I now come here seeking your help as I look for this missing piece. Apparently I just missed one on eBay (although it was grey--mine is black), and while I'm not sure how likely it is that anyone can help me, I figured it was worth a shot. Of course I'd be willing to cover shipping and pay whatever you think it's worth. Thanks for looking!

Pic is what I believe I need. Not sure what model it is or if that matters, but it's a US console.Attachment 5297
