It doesn't appear that Kobold Pelts needed to complete the 
Kobold Killing quest are dropping off kobolds in Toxxulia Forest.
Initially, I thought it might be due to them being added in some later patch (with The Hole or The Warrens perhaps), but these Everlore snapshots from 1999-2000 for 
Kobold Runt, 
Scout, 
Sentry, 
Shaman, and 
Watcher list Kobold Pelts as a drop. This Jan. 2000 comment from the Kobold Scout entry mentions turning them into "a woman in the warrior guild" (Tabure Ahendle) to complete the quest:

 Here's an Oct. 1999 comment from an Everlore snapshot of the 
Kobold Pelt item:

 Also, the above Kobold entries indicate a faction hit of -Kobold upon death. Currently, no faction hits are present. This could provide pre-Warrens faction evidence requested in this 
thread and might also explain how new erudites (evil ones at least?) initially con indifferent to Toxxulia kobolds as Telin's 
post suggests.
