Here's a mini for the cowl:

http://backpack.tf/profiles/76561198182399626#!/compare/1471046400/1471132800 Added 1 Key for an Orbiting Fire Head Warmer(22 Keys)(21 Keys total)

http://www.tf2outpost.com/trade/28413476 B/O was 20

I think it's fair to call 20 an outlier given all the sales above it, and how old that sale is. 27-31 would be better here.

thanks for all the peeps for help
