"Sale 10 looks like it was for a Winning Spirit Burstchester + ~5 Keys of Items

https://backpack.tf/profiles/76561198167761436#!/compare/1740096000/1740355200

The Burstchester has no other sales, but it has a generic buy order at 4.3 Keys, so that'd make this sale round to 9.5 Keys.

Assuming this is the history that corresponds to the Marketplace sale, it looks like whomever bought it dumped it to STN.
