Sad to see c0Rn!x not pricing unusuals, but at least I can actually price some pipes now :P

3 of 3, and all three of them have had recent sales, so here goes nothing :P

Sale 1:

(No Outpost trade) http://backpack.tf/profiles/76561198065780780?time=1429513200 to http://backpack.tf/profiles/76561198065780780?time=1429599600 (Buyer BP) http://prntscr.com/71ogzn Appears to have sold for 17 keys (Note that all the other new items besides the pipe were not from the seller)

Final sale value: 17 keys (Sold in one day according to the item history, so calling this a QS)

After that, the history gets really weird, as I can't even find that 雲吞OsCaRLIU<TW> or http://www.tf2outpost.com/user/320292, as it says in the Outpost but not backpack.tf history had it at all, and all of Scrooge S> Pro KS Aust Sniper's unusuals all seems to disappear on the same day for no visble return at all http://prntscr.com/71okrl .

Sale 2:

http://www.tf2outpost.com/trade/25509996 http://backpack.tf/profiles/76561198034216168?time=1427526000 to http://backpack.tf/profiles/76561198034216168?time=1427612400 http://prntscr.com/721tzu Sold with 2 keys in sweets for 15 keys pure

Final sale value: 13 keys

Sale 3:

http://www.tf2outpost.com/trade/25522839 http://backpack.tf/profiles/76561198069118738?time=1428044400 to http://backpack.tf/profiles/76561198069118738?time=1428130800 Sold for a Stormy Attendant, outdated at 27 keys, mini at 17 keys, and as overpay was applied in the mini, it doesn't need to be again.

Final sale value: 17 keys

Attendant mini:

http://www.tf2outpost.com/trade/25846379 http://backpack.tf/profiles/76561198101983009?time=1430377200 to http://backpack.tf/profiles/76561198101983009?time=1430722800 Sold with an Aces Slick Cut, 11.5 keys, 10 keys after overpay, (Ironically updated yesterday, thanks Mindacos), for 19 keys pure

Final sale value: 9 keys (Took a fair while to sell, so not a QS, but calling it an outlier, as it sold with another unusual, not making it as accurate, and because how far it is from the other sale and the old price.)

Mini sale 2:

http://www.tf2outpost.com/trade/25592635 http://backpack.tf/profiles/76561197999308255?time=1428649200 to http://backpack.tf/profiles/76561197999308255?time=1428735600 (Buyer's BP) Sold for a Blizzardy Stove Pipe, worth 14 keys, and a Strange Spec. KS. Festive Grenade Launcher, worth 5 keys at the time.

Grenade Launcher 'mini':

There is currently a seller selling it at the current price it is with Spec. KS, http://prntscr.com/7227q6 , and with Gib Kills http://prntscr.com/7227yv , and with overpay, the ramining part would be pretty much 5 keys anyways, so just taking it as it's original value.

Sale value: 17 keys after overpay

Mini value: 17 keys

Sale 4:

http://backpack.tf/profiles/76561198152335671?time=1429254000 to http://backpack.tf/profiles/76561198152335671?time=1429340400 Sold with 2 keys in sweets, after overpay, for a Lvl. 27 Max's Head, which was 27 keys at the time (Level 27 for 27 keys :P), no overpay required I believe because of the level, plus the pipe appeared to be offered, because it did not have an Outpost trade, but the Max did ( http://www.tf2outpost.com/trade/25723267 )

Final sale value: 25 keys

Sale 5:

http://www.tf2outpost.com/trade/25808266 http://backpack.tf/profiles/76561198055163381?time=1430232392 to http://backpack.tf/profiles/76561198055163381?time=1430290800 http://prntscr.com/722g1e Sold for 19 keys pure.

Final sale value: 19 keys

Other sales on that hat are very iffy, like Antonio bought his for a higher tier for lower-tiers, Fattie is Outpost banned for scamming, making his sales invalid, Boopba's sale involves it selling for a higher-tier HWaH, with another hat, so it should be used to price it, and he bought it for a higher tier headspliter and got it with a Scorching Beanie, which I will use to price the headspliter, and Triple's sale was literally for negative keys before factoring in the price of the pipe, so I didn't even bother to list it.

With sales at 13, 17, 17, 19, and 25 keys, going with the wider but more accurate range of 17 to 25 keys, as the 25 sale was pretty much pure, 17 is too common, and one of the sales was pure, and calling the 13 key sale an outlier, as it deviates a lot from the other sales. It would be greatly appreciated if you pointed out any mistakes I made, as it is 2 AM where I live now, so I am bound to have made a lot :P. 5 hours and 4,000+ characters, gg cruel world...
