All credit goes to the Real Slim shady, thank you for helping me suggest this by providing item histories of these recent sales :)

https://backpack.tf/item/1639845948 (duped)

I don't really see any sales here, much less a valid sale. Assuming there is a sale, the date would be October 21, which is outdated as of tomorrow, excluding unless I see evidence otherwise.

Talked to the owner, he never sold it, just let friends borrow it, no sale here.

https://backpack.tf/profiles/76561198138337403#!/compare/1639612800/1639699200 - 160 (Taking Aussies at buy orders, they are always close to sales)

https://backpack.tf/profiles/76561198002391950#!/compare/1635984000/1636070400 - 225 for the Belt + Kill-A-Watt Crone's Dome

Not sure how to price the Crone's, it's buying for 65 and has sell orders at 125~, no recent price suggestion

I won't count it, but if the crone's does get suggested, the overall sale here for the belt would be within a 130-150 price range

https://backpack.tf/profiles/76561198114402400#!/compare/1638662400/1638748800 - 150

Sales:

126

130

135

140

140

140

150

Taking 140-150, this looks like the correct price according to sales and listings. 126-135 seems too low, the three 140 sales are definitely the correct price.

If there is anything else I need to add, I would be more than happy to correct anything :)
