Ok... got it. I don't think you're asking about the models so much as the "timeline" on which the models happened. The only thing I can figure is that one of those feet is either Posette or Judy, and another is Victoria. This causes a problem, because Posette's feet came first, meaning that she and Judy will share their mesh. But Victoria was supposed to be built from scratch, wasn't she? There is no way, that if one of those feet is Posette or Judy, that Vicky's foot is based on a 3d-Scan. Just as a guess, the odds that any of those feet at all is based on a 3d scan are slim. So, are you implying that Vicky has Posette's feet?
