Sold for 40 Keys(Is pretty much outdated today, probably not valid to use)

Bulk for SFB Combustible Kabuto(should be used to update the kabuto)

http://backpack.tf/profiles/76561198151087213?time=1444460400 (October 10th)

54 is an obvious outlier, because of the sales and B/Os at less. 40 Key sale might be old, but it supports the drop.

This was previously updated out of duped sales, so they're fine to use. 35-38 Keys should be fine.

Additional Proof/Counter-Proof/Constructive Criticism/Feedback is always appreciated.
