I won't comment on vintage vs. current US Old Spice, but the difference between current US (P&G) and India (Shulton/MCPL) versions is, as others have already note, fairly obvious and striking, and variables such as freshness and evaporation are not an issue.
I am an OS India fan. Just as inexpensive as the US stuff if you can source it locally.
