Just FYI, this is what a stuffed gear looks like - you cannot see the wear if you look directly at the side profile of the gear (as in your pictures) - only when you view the gear from the edge.
The gear teeth should be flat in this view - like at the bottom of the gear. The wear is the curved hollow at the top.

I'm not saying you missed this (I'm sure you didn't) - I'm just adding this to the thread for future readers.
