These have somewhat of a range, and they also need a bump considering the last one was 5 months ago.

SELLERS

http://www.tf2outpost.com/trade/9249057 - Selling for 1 scrap. Got offered .05 for 1 (Hi Jymotion)

http://bazaar.tf/trade/129184 - Got offered a scrap for every uncraft the person offering doesn't have. He commented on an uncraft L'Etranger trade.

http://www.tf2outpost.com/trade/9059815 - Has a grayed out L'Etranger, so it's most likely that he sold it.

http://www.tf2outpost.com/trade/2282331 - Offered a weapon for the L'Etranger. Got rejected because seller is most likely looking for 1 scrap.

BUYERS

http://www.tf2outpost.com/trade/8266966 - Was buying uncraft weapons for .11, but got closed for being inactive. Specifically looking for L'Etranger.

Summary: Very hard to find sellers that had offers or buyers for the most part. It's in a polycount set, so uncraft collectors like to look around. Please feel free to provide counterproof if possible. Thanks for your consideration.
