Black Sea Man should have potato leaves and should not terminate in a double blossom

I accidentally picked up a weird seedling at Tapia Brothers Tomatomania this weekend, does anybody know if there are any Black Sea Man plants left there so I can go back and get the real thing?

Also does anybody think this freaky "sunflower"-format seedling is worth planting out? It seriously just terminates in a flat stem and a double blossom.
