The original wheel rubber is cracked and splitting in places, I do use this grill occasionally when I'm feeling nostalgic or only doing a couple burgers/brats. It was my Grandfather's he got it around 1974 according to my Dad. I would say that it was NOS in '74 since there is no patent and thumbscrews are present. My Uncle owned an ACE Hardware store in central NE at the time and gave it to him and my Grandmother as a house warming gift. So I'm guessing 1968 at the latest for the grill's age, maybe 1969. Everything is original including the ash pan. I restained the handle dark walnut last year. I love the metal hubs on the wheels, I would love to know how to restore them. Whether I replace the legs to keep it fresh or restore the originals, nothing on this grill is being or needs to be thrown away. I'm just pondering the idea.
