World of Warcraft. Quests - Crashed Sprayer

Specialist Cogwheel at Drak'Sotra has asked you to collect Plague Sprayer Parts.
Description
I know that one of those plague sprayers crashed somewhere within Drak'Sotra to the west of us.
Why don't you see if you can find it. I can use the parts from the sprayer to create the device that's going to bring those things down!
