This forum is pretty awesome. You were asking a question about a grill, of which there are two known examples on the entire planet, where the information that could also help you involved poorly selling grills that haven't been in stores in over 30 years, and you got exactly the answer you were looking for, in a little more than seven hours, from somebody on the other side of the planet. Bravo, @Hogsy and @AZRaptor! God Bless the WKC!
Just for reference, I have an older (heavy metal base, no louvers) kettle gasser, and the handle is double riveted.
