It's the Credo Northman armor, so I'm pretty sure it's your armor. It wasn't packaged with this specific mod though. Either way, I've had one or two bugs that were corrected by reverting to an earlier save. For whatever reason the Whiterun guards were in their underwear but they had your customized shields. When I reverted to an earlier save they looked fine. Great work guys, and Merry Christmas to everyone!
