I've never seen that color in a Master model, but I guess it's possible. My dbase of the last 107 or so that were offered shows all those in that color to be Experts. I could be wrong, just haven't seen one.
By the time you clean it up, re-wrap, re-saddle, and get those hoods clean, it will be pretty, indeed. Don't let the colors fool you, it's a great bike for the price and will run w/the pack.
I watched that auction. I think there's 5 more out there for sale right now.
