Waiting to see what happens with the 4 ref postings, as they were listed just recently.

Unsolds:

Found these, don't really care to delve into more. I will admit it is difficult finding any evidence since sales are so little with this item. I tend to find outrageous pricing due to low craft numbers or "Area 51" fanatics looking for craft number 51. Downvoting but hats off to you for tackling it.

EDIT: Just realized the backpack.tf link has duplicates from the trade.tf links, sorry about that.

All young, yes, but with only one piece of proof at 4 ref after a week and updates only showing more sales for 2 ref, I don't see how 2 ref can be left out of range. Even if frequently quick, it's overwhelmingly the most common trading point.
