You know, I wouldn’t be surprised if that was a repack. I could see the following scenario: someone trying to strip the battle damage accidentally stripping some/all of the trim paint on the abdomen. They then ‘cleaned up’ the area by stripping all the paint (so it looked more passable), repacked the figure, and returned it for a refund/exchange. I obviously don’t know for sure, but that explanation seems more likely than a random factory miss. At least, it seems more likely to me.
