Thank you! This is all tremendously useful information; I am doing the quest on Vox with my level 22 Vah Shir Warrior and have just reached this stage of Gifts of Steel, having collected all the other items. Star date 21.04.2020!

There is a static spawn at /LOC -1632, -568, 240, North and slightly east of the Gunthak boat. Spawns timer is very short just 3 minutes. And one will wander by this spot too. He does Not drop the Stoneforger's Lore every time.
That is such a super help, thank you! The given description, that it spawns among the kobolds in the southern part of the zone, is so misleading! I can only assume that was to prevent the task from being too easy.
