https://backpack.tf/profiles/76561199187662740#!/compare/1710460800/1712188800 ~ buyer bp doesnt go back far enough

There is a possibility that it was sold for the 11 keys that was used to purchase the bombing run, https://backpack.tf/suggestion/66074c7b55c87146fb0f1e41 but I can't see a proper match on the bots end.

https://backpack.tf/profiles/76561198176218038#!/compare/1711065600/1711152000 ~ sold with a Miami Nights Dread Knot for a crustcean brolly. Knot open sugg at 10 keys making this 7.5 key sale https://backpack.tf/suggestion/65e7c072ac79191d3601ad2e , most likely outlier/bulk anyway.

Item History #2: https://backpack.tf/item/11986393756

https://backpack.tf/profiles/76561199245733895#!/compare/1704412800/1704499200 ~ ? it's OJ known gambler so its hard to say with his sales, whole bp moves.

https://backpack.tf/profiles/76561198096044051#!/compare/1704412800/1704499200 ~ buyer side doesnt show anything sensible.

Rest of history is gambling.

Item History #3: https://backpack.tf/item/12011598614

https://backpack.tf/profiles/76561198064851728#!/compare/1706227200/1706313600 ~ traded to STN for.. 4 unusual taunts all unpriced. We don't know what stn valued them at or what the brolly was valued at :(

I can say they do buy it at 9 keys 28.11 ref https://stntrading.eu/item/tf2/Unusual+Soundwave+Undercover+Brolly so that earlier sale is definetly an outlier.

https://backpack.tf/profiles/76561198311498888#!/compare/1706227200/1706313600 ~ ?

https://backpack.tf/profiles/76561199111073161#!/compare/1705622400/1705708800 ~ sold for 14 keys

https://backpack.tf/profiles/76561198057420310#!/compare/1705017600/1705104000 ~ sold to buy orders for 9 keys + 60 ref. Some of the histories show Carl for the keys but Carl/Harry are one-in-the-same, same owned and do shuffle around keys to each other so it would make sense that Harry may not have been in the history if Carl sent Harry keys for restock.

= 10 keys

Item History #5: https://backpack.tf/item/11920958084

https://backpack.tf/profiles/76561199084784906#!/compare/1707350400/1707436800 ~ ?

https://backpack.tf/profiles/76561199127652476#!/compare/1708214400/1708300800 ~ 13 keys

https://next.backpack.tf/profiles/76561198117853826/compare?from=1707955200&to=1708300800 ~ this shows 19 coming in but as seen above only 13 leave shpee bot's.. the rest are from johan which it appears on the seller side he sells his taunts to... so I am confused why they have similar id's.

Also seller for 9 MONTHS at 16.. so it doesnt make sense a bot wuld pay 19. so Going to assume this is a weird bug and take 13, the keys that actually have shpee in the history.

Extra:

https://marketplace.tf/items/tf2/31262;5;u255 ~ April 1 2024 $29.95 / 1.67 = 18 keys.

Sales @ 10, 14, 13, 18.

Excluding 18 due to the seller at 16 for 9 months and listing at 14 prior for almost a month (seen here https://next.backpack.tf/classifieds/snapshots/Soundwave%20Undercover%20Brolly and here https://i.imgur.com/6ICIFV6.png )

Since I can't exactly 100% verify the 10 key sale, and it is pretty close to buyers at 9.1 + STN, I will take 13-14 here instead.

New sales:

https://backpack.tf/profiles/76561198850178158#!/compare/1710460800/1710547200 ~ 17.5 keys in items. still x2 sellers at 16 so outlier

https://backpack.tf/profiles/76561198397542560#!/compare/1712880000/1713657600 ~ <10 key seller so below buyers (stn buyers for over 10 keys)
