In this group of keys, we’re looking for ones that have a similar ID to 17411741427 under the taunt seller’s name. While the last 10 keys have their name in the history, only the last 8 have similar IDs. Therefore, we can assume those 8 keys were involved in the trade for the Mannrobics taunt.

The 8 keys + the 1 key and 29 ref that match in the seller’s original compare link add up to 9 keys + 29 ref, which closely matches their B/O.

This sale also occurs after their marketplace purchase on July 24th.
