Dogger https://backpack.tf/item/1867804523

Reasoning

He rejected 10 keys then accepted it, and i thought it was 10 keys, however, on the same day he sold the OF Dogger, he came across the KaW Dogger https://backpack.tf/item/2540481290. But he didn't trade the OF for the KaW. I went to track the sale for the KaW and I found this http://gyazo.com/67ac27985cab386e42c09346709ca1c9, the KaW Dogger was sold for 11 keys as opposed to 10. The buyer of the KaW had no other keys in his inv at the time of the sale. It is fair to say he sold it for 11
