(Price check) Strange Festivised Rocket Launcher, Strange Part: Buildings Destroyed

[critter]

i got this in an auction and i have no goddamn idea how much this is worth, though i know how much a festivized strange launcher is worth i dont know how much value the strange part adds. the buildings destroyed strange part itself sells for around 3 keys and seems like a good fit on a rocket launcher, i just dont know the exact value it would add. if anyone would like to buy it just let me know, thanks

Only worth 2 keys 

Parts/KS/war paints/festivizers loose some of their value when applied

sounds about right, the links showed in the first reply either have multiple parts or are killstreaked so this is probably the most accurate price. thanks
