Thanks to Offline for correcting sales:

https://marketplace.tf/items/tf2/355;3

August 24 - $44.99 / $1.81 = 24.86 keys

August 30 - $44.99 / $1.81 = 24.86 keys

these aren't countered by buyers

-> rounding up to 25k

No other recent sales on other variants, or any variants for SCM: https://steamcommunity.com/market/listings/440/Vintage%20Fan%20O%27War

Sale at ~20k is countered, so taking 32k flat (also no sales on other variants).

I know realised that I excluded the MP sales initially cus I used them in the previous suggestion, but I guess including them is okay too.
