A used Exhaust Cover from a Homelite UT20811B grass trimmer power head.  The machine it came from was a running weedeater.   The machine reads "Homelite" made by "John Deere" with a 25cc engine manufactured in October 2001.  The Markings on the shell read "Homelite", "Versa Tool", "Zip Start", Model UT20811B.  Look closely at the photos, they are of the actual part you are buying.
