Sale 5: Appears like STN sells to 커햄, but the item reappears in buyer's inventory un-tradable, at a different level. This is a different item, which you can find the history for here: https://backpack.tf/item/652170583

There's a sale history on SCM on May 14th at 5am, hat appears in buyer's inventory untradeable.
