4 month old price, I'm pretty sure this is what all the other suggestions I've done today have been for but at this point I can't tell if this is being used for another hat or not.

http://backpack.tf/profiles/76561197999106798?time=1405321200 (After, 5 new buds and 5 new keys with most having a matching history. Not a stretch to assume that even those with a non-matching history were included but just not scanned in the other persons backpack)
