How did you figure out 36 keys? I can't seem to find any of the keys you mentioned from the backpack history that you provided.

http://backpack.tf/profiles/76561197960788095?time=1421222400 Just checked the keys before the trades one by one and it seems that 42 keys were identifiable being traded from creamy to raiden. There might be more to it.

Either way, this is inaccurate. Please add the seller or buyer to confirm the final trade. Closing this for now.
