I don't have a 2004 Weber Catalog so I don't know about that year. Catalogs for 2005 and 2006 both show enclosed cabinet for Genesis Silver C, then 2007 changes to the E-320 design with side burner moved to the left side.I think it is a Silver C from 05’. Can anyone help confirm?
It stands for Stop Watch Engineering. It was a buzzword with Weber for awhileI think the SWE designation has something to do with ease of assembly if I recall correctly.
