scrap auction

->

https://backpack.tf/profiles/76561198110834357#!/compare/1637539200/1637625600

owner who presumably put up for scrap auction received ~27k from new owner, so 27k

https://backpack.tf/profiles/76561198143589141#!/compare/1637539200/1637625600

only 10k matches, but the seller presumably bought the ge bombing run the same day for ~24k https://gladiator.tf/listings/619d163084578a4767da7ba8, and since 4 keys leave the seller's compare on the same day, I think it's fair to assume the seller received 10 + 24 - 4 = 30 keys for selling this hat,

B/O at 35k https://gladiator.tf/listings/619c8d356c6b5426bc497664

(I think 30 also matches on keys leaving buyer's side)

only some ref matches so untrace, gladiator suggests ~27k

generic buyers for s. unu TYS are at 27k, other 27 sale was also at auction.

30-40.
