Check out doubleddie.com. That's where I go to check out these center bay ddrs when I findd them. John Wexler has complete listing for many of the dates and it's an easy site to navigate. Looks like it might be WDDR-019.
EDIT: or on second thought, maybe not that one, but one that looks similar. Unfortunately, many of the images aren't loading on my mobile right now, so I can't check for sure. There's about a hundred ddrs for that date, most of them in the center bay. Some of them are quite interesting, with strong doubling.
