Sold for a Demonflame Napper's (~5.2) - outlier

http://www.tf2outpost.com/trade/19740562 - 4.5, 1 month

http://www.tf2outpost.com/trade/20103126 - 4, very young

I actually am not certain how to price this, only pure sale is well below current range and the other one is slightly above. 4.5 end comes out of the "quicksale" buyout which is lower than one of the recent sales, 2.7 is considered an outlier due other sales
