Current owner has an offer os a HOUWAR "to start" http://www.tf2outpost.com/trade/6954697 - and says it's low. He paid this for his http://puu.sh/1AACf (the hats are seen here http://www.tf2outpost.com/trade/6895522 ). This is about 13 Earbuds if you consider how much Strange Festives were worth back then (a week ago). The previous owner also had a B/O of 15 at one point http://www.tf2outpost.com/trade/6829598 . Can't tell how much the first owner got http://www.tf2outpost.com/trade/6283264 but from this trade you can see he wouldn't take just 10 http://www.tf2outpost.com/trade/6208215 .

The other one was previously owned by this guy http://www.tf2outpost.com/trade/5996172 . He sold to NT Wazoo, and from item history you can see he got these two hats http://www.tf2outpost.com/trade/6025221 (4.5+5.5 currently. At the time the Berliner had no price though). Current owner of this hat seems to be a Drill collector so it won't be on the market again probably.
