Tankatronic Goggles

The Tankatronic Goggles is a TBC head item crafted by Engineers. It is one of several item-level 127 epic engineering goggles. It can, like the other goggles, be "upgraded" with a recipe dropping in the Sunwell Plateau. The upgrade for the Tankatronic Goggles is the Hard Khorium Goggles.

Source
This item is crafted with Engineering (350); taught by trainers.

Restrictions
Only Paladins and Warriors with 350 Engineering can train this (likely Death Knights too, although this class did not exist when the goggles were implemented to the game). The same restrictions can be seen in the TCG.
