http://www.tf2outpost.com/trade/18221914 The second, and recent sale. History is botched from Kyrannn to Mizore due to being switched between Ohai, Boat, Fite Me, and Shab to broker for each other.

Final sale was a Knifestorm Hermes (4.6~), Ghost Bubble (3.6), Purple Fetti Reg (1.9~), Noble Flies (1.7~) + 19 keys pure (1) + SF Amby (.3~).
