I think it is authentic but there is one weird thing. The padding over the turnlock looks crooked. I've never seen this on any Willis before. Usually on a fake, the padding is missing or the wrong shape.
Wow I would have never noticed the uneven padding. Did you see the bullseye on the creed? Could it maybe have been sent to the outlet for a manufacturing error? It's not crooked enough for me to mind but I definitely don't want a fake. I'm glad you still think it's authentic.
