Buyer from above. Not sure, but both GC Translator and KaW Tricorne would support ~20. Better ignore both sales.

KaW Front Runner (unsold at 20 for 3 months, proper mini needed)

https://backpack.tf/profiles/76561198055622215#!/compare/1531267200/1531353600

I would mini the Front Runner and give this a range.

The 39 key buyer resold for what appears to be much lower, so both sales should be ignored. If I didn't miss anything, then 18-28 should work.

Ugly range but none of the sales are being countered as far as I can tell.
