Sweet! Was this the one from eBay ?
It was the one from eBay. The legs are a little rusty but I plan to take them off and paint them.
There is no letter code on the vent, is there any way to age these? It has welded tabs to hold the cooking grate rather than a groove in the bowl. I looked in the old catalogs here and in '73 there was no bowl groove and in '78 there is a groove. That is as close as I could narrow it down. I really enjoy looking through the old catalogs, I wish there were more available.
