Not sure what the point of showing a non Weber grill is , but I'll play along
I found that stuff looking under Weber patents........surely not something they put out under their name, but perhaps a one off production like the Sears Econo models>>>?
.....or, another possibility might be scooping up patents so they somehow don't later compete>>>?
Also, if you look closely, it's a patent ONLY for the leg system, not necessarily the actual bowl section.....
