Buyer: https://next.backpack.tf/profiles/76561198882175555/compare?from=1761436800&to=1761523200 -- untrace 

- 16342511285-16342511452: UBFC, Minigun and a single key from the seller

- 15846981209-16337828516: 

  - UBFC: as per old range, assume 28 keys  

  - https://next.backpack.tf/item/15846981209 (Str.Sp.KS Minigun): 3-4 keys as per SCM, assume 3.5 keys

Total: 7x2 + 8x2 + 28 + 3.5 = 61.5 keys for the sole https://next.backpack.tf/item/15846981209 (Cuban Brand Loyalist) from the buyer. This fits CBL's price of 60-63 keys, but that price is 5 months old. Assuming item overpay in mixed offer. This will not affect the final price suggestion, since there is another sale of UBFC at 28 keys so, lower end of the final range will not change.
