You can redo that one

Theres another sale where it seems to have sold for a blizz fukaa + maybe other stuff, but I dont know what was involved and what was not:

http://backpack.tf/profiles/76561198149302119/#!/compare/1455264000/1455350400

its a weird one and I wouldnt use it directly, but it would call for a range.

I guess you can go 23-32 here
