Item 3: https://backpack.tf/item/16676043681

Sale 3: Untrace, presumably bought off of STN then put on MannCo, no keys incoming of similar value and no shared history

Sale 2: Sold same day by STN, there's a 42k 1 ref bundle incoming from Pamit, but nothing matching up with the Operator, even minus the 61 metal that's 133k~ outgoing and 42k for the Blizzardy Storm Winter Woodsman which he receives from the same bot, it's maximum 91k which is below buyers. Hell even if the full 133k was for this, it would still be an outlier.

All movements of the PE Deep Cover are unusable, except a $179.99 sale on Jan 1st, but with 3 unsolds at $154.99, it's not useable. Microing at buyers of 51.8k: https://imgur.com/a/2RxtmeN

51.8k + 80k = 131.8k for Sale 3.

Sales at 131.8k, 163.93k, 165k, and 178.37k. Excluding 131.8k as an outlier, and 178.37k as above current unsold (only 9d old, but also helps since I'm removing the low sale). Taking 163.93k rounded up to 164k for the low end, and 165k for the high end in a silly 1 key range.
