Since only one was found so far, i do not believe it can be considered a legit back variation (right now). at the moment it's a very cool color "error", but that's it. once a second or third one surfaces, then it'll be a different story.

FWIW- i'm not taking anythign away from the Blue OM; i saw the blue old mill in person, it is legit and very cool...just not sure it can be considered a back that everyone "needs" as of yet.
