The problem with this is not all of them say "Polo I, II, III or IV". One of mine says "Blue Label". I know the Bradford fits good on the jacket, but the pants are tighter than Incotex. That surprises me. I just checked my Polo coats, and all of them indicate the model on their tag. I've stopped buying OTR, so most of these coats are a few years old. Perhaps they've changed.
