Ancient Mechanized Ethian Steed
This mount is part of the loot table from Uncle Stans Lure. It is possible that this mount was removed from the lures loot table.
I was told by a player in game today (8th December 2019) that they had fished up this mount with Uncle Stan’s Infra-cell Lure today.
It is possible that this mount is only on the loot table for that specific lure, or it could be on the loot table for all 3 lures.
