From the angle that the bands are photographed I can't tell the sort of finish that they are Parked or Blue but one tip that I was told is if it's blue it should/tended to be a dullish blue if original. If it's a really shiny blue it's more likely to be a reproduction. One trick which I used on a U.K. deactivated 1903 Springfield that had a band which was obviously fake because it was far too shiny was to round off the square edges, bead blast it, phosphate it and then re-blue it. It ended up as a dull blue with slightly rounded edges and it then didn't stand out like a sore thumb as repro.
