Sorry about the confusion guys. I guess I should have specified what I meant. I was referring to the numeric labeling of the old vintage grills of the 1960's and 70's. I couldn't remember, but I thought 3000 series grills were the 18.5 and the 7000 series were the 22.5 grills and 8000 series were 26.75? Just curious, but did the old vintage Ranch kettles have any number assigned to them? Maybe 9000 series or something like that?
