Sold for Hot Field-Tested Night Owl Sniper Rifle + ~4 keys in metal/items

https://i.imgur.com/tInGZtg.png - considering the buyer at 23 on the Sniper Rifle, this sale is most likely going to exceed at least 28 keys, which is significantly higher than the sellers at 22 and 25. (the seller at 25 is also the buyer of this sale) Excluding this sale for that reason.

The skin matches, as well as a random weapon, but this isn’t gonna help us.

Excluding 27, due to the cheaper sellers, though I probably wouldn’t have excluded them if they weren’t so ancient.

Taking 20-22.
