Can't really find much for this thing, 90% of those on outpost are either already sold, craft #d or painted.

1 is untradeable, 1 is craft #d, the other one is selling for a key (owner has been offline for most of the time since the post was up)

http://www.tf2outpost.com/trade/16047999 - Instasold for 5 ref

http://www.tf2outpost.com/trade/16064587 - Instasold for 5 ref

http://www.tf2outpost.com/trade/16059846 - Instasold for 5 ref

http://www.tf2outpost.com/trade/16034376 - Instasold for 5 ref, had lost of willing buyers.

http://www.tf2outpost.com/trade/16042090 - Same as above, different seller

It's actually rather difficult to find one for less than a key (or even find a regular one at all), <6 ref sells very quickly.
