Runner (the buyer of the hat) bought keys directly from a key seller, so the compare links and item histories read incorrectly.

I also withdrew the hat from a Marketplace.tf bot which further complicates the histories.

The previous sale was untraceable through PayPal. I originally bought it in bulk alongside other Unusuals, sometime between the 24th and 25th of November. I also bought 600 keys from another user with cash that day. It doesn't show anywhere in my compare links for those days. I include both sales in the screenshot of my trade history.

However, I deposited it to Marketplace.tf bots immediately, which could explain this.

A nice hat to add to your collection!
