Sold for DBD Marauder (25.5) + Stormy Brainiac (Outdated at 26.5)

There's two week old sellers on the Brainiac at 25 but a buyer at ~20 ( https://backpack.tf/stats/Unusual/Brainiac%20Hairpiece/Tradable/Craftable/29 )

So this is going to be in the ~20-25 area, enough for me to round to 50 overall and not need any more precision.

= 50
