https://backpack.tf/item/11573961458

Untraceable, 3 keys match. Didn't bother checking the buyer's metal, but given current sellers it shouldn't matter if gladiator is correct anyways.

Untraceable. Dunno if traded directly with the next in history, but the "buyer" here is a scammer.

5 may currently seem a little high here, but a recent gladiator purchase at 4 keys + 56.11 ref (#14) would suggest this thing needs a high-end.

Taking 4-5 for now.
