Value is also off as a result of the Gibus being adjusted.

Another sale from the same timeframe:

https://backpack.tf/profiles/76561198289219099#!/compare/1504656000/1504742400 - Buyer's side - Warm-Up and Wear match (both outdated though), Bunsen does not

https://backpack.tf/profiles/76561198195731583#!/compare/1504656000/1504742400 - Seller's side - Shows that keys were also involved, likely part of what the Bunsen was sold for, but still unclear if there were more

These sales are fairly different value -wise at any rate. Should either get full confirmation of the sale I linked, or wait for a third sale here.

https://backpack.tf/profiles/76561198069813252#!/compare/1513036800/1513123200 sold for 20 keys here; was probably brokered inbetween explaining the weird histories.

Sales seem to be all over the place on this, so its best left unpriced for now.
