I'm far from an expert, as I've only seen one in person before (true vintage) and my memory is kind of fuzzy. That looks real to me though. Any labels hidden inside the pockets on on the inside seams? That would be a tell-tale sign of a repro. I also think these were made well into the 50's, so even though it may be vintage, narrowing it down to a specific decade may be the tough part. Either way, vintage or not, that is a killer find.
