There have been citrus mod sets lurking under Black Panther but most BP sets are just BP. The citrus Mod ones were shells they had already wrapped that were sitting around the plant waiting for orders that never came. At some point they decided to just cover up the unpopular wrap and move them along. BP was the only thing thin enough to go over another wrap without making the shell oversized. But how many CM sets did they have sitting around unsold? 10? 20? Even if they'd made up 50 sets worth of CM drums in anticipation of future orders (unlikely) that would still represent a small percentage of the BP sets they ultimately sold. People do luck out finding CM drums but it's sort of in winning the lottery type odds (well) probably better than that but still a longshot)
