Note from worstcaster. I am really sorry but Cogsworth has gone missing from the cache. There were 2 people who logged they took a TB out so if you try PMing them, you may find he is OK or they placed him without logging him.
Here is the URL to the cache where Cogsworth was: http://www.geocaching.com/geocache/GC2RAK0_the-barren-stretch-cache?guid=f819dff3-ae60-4bd0-99dc-ee4529910d97
