Link 1: http://www.tf2outpost.com/trade/17493903 Sold for Stormy Barn

Link 2: Didn't go to the guy with the berliner...

Link 4: http://www.tf2outpost.com/trade/16958921 Sold for Blizzardy Hallmark

Link 5: http://www.tf2outpost.com/trade/17007520 Sold for SF Scatter

Link 6: Not sure about this one but looks like it sold for http://www.tf2outpost.com/trade/16802224 a smoking Executioner through perhaps an alt? Histories are really mingled and that's the best I can guess for.

Going back to sleep now, have fun calculating original prices and overpay.

First link sold for stormy barnstormer (2-2.3 very old price)

Second link sold for GBH data mining light (3.2-3.9 old price) + sweets: http://www.tf2outpost.com/trade/17437576

Third link was sold for n+b pencil pusher (15-17 keys) + sweets: http://www.tf2outpost.com/trade/17061934

Fourth link sold for blizz hallmark (1.8-2, slightly old price)

Fifth link appears to have sold for s.f.scattergun, unknown if other things were exchanged

http://www.tf2outpost.com/trade/17857660 - BO 2 buds

http://www.tf2outpost.com/trade/17781972 - BO 2 buds, unknown sale price

http://www.tf2outpost.com/trade/17652893 - offered 35 keys, but sold to someone else

After overpay is considered, there isn't justification for a 2.4 bud high end. Also there is a new trade with a BO of 2 buds, but it's still a bit too young to be used as definitive proof.
