https://backpack.tf/profiles/76561198232041512#!/compare/1626566400/1626739200 - 2 Logo Screamin' Eagles (34 Keys) + C9 Gibus + 72 Fubar

https://gladiator.tf/listings/60f6c0e483c738069d0050db - The Eagles sale rounds to or is capped by the buyout of 70 Keys

https://gladiator.tf/listings/60fcfc204e4032be9386dffb - The Haunted Ghosts Rifleman has had a seller at ~70 Keys for a week now, so 80 is likely high

https://backpack.tf/item/8285662382

Taking 70 for the Ghosts Rifleman makes this sale 145 Keys, but this has had a seller at 100 Keys for a month now, suggesting 145 is high.

Because the only traceable sale for the Insomnia Rifleman is well above the month-long seller at 100 Keys, I'd wait for another sale before updating this.

As such, this suggestion will need to be closed.
