Was used in the Engineer’s Cap suggestion, but wasn’t used to set a high-end. Irregardless of whether or not it gets used here, it will not affect the range here.

http://www.tf2outpost.com/trade/29195103 - 2 weeks

Sales at:

16

17

20

28

28 is an obvious outlier, and would be much lower if the B/O was present. Excluding 28.

16 sold rather quickly, and possibly to a quickbuyer. Excluding 16.

Going with 17-20.
