Going to close this. My reason being that I won't have access to my laptop for a while, and I did manage to find another sale. This is what I had achieved so far:

Sold for Haunted Ghosts Naggenvatcher + Duped Chiroptera Venenata Strontium Stove Pipe + ~18 keys in items

http://www.tf2outpost.com/trade/27518041

http://backpack.tf/profiles/76561198076269357?time=1449475200&compare=1449561600 (Seller)

http://backpack.tf/profiles/76561198096389539?time=1449475200&compare=1449561600 (Buyer)

X = (80 + 52 + 18)0.9

X = 135

Only sale I found on the strontium stovepipe was a Nuts n Bolts Master's Yellow Belt + 13 keys, which seems really low. There were other sales, but I couldn't trace them. Going with the regular price on it.

If someone wants to resuggest, feel free to do so.
