My understanding is that it was a grill sold in Australia. I believe it's a Summit 400LP. It does not have a lid, the top slides off. I figured I could use it like a hibachi grill and like you I have never seen one before so I thought it would be cool to have.
Chad, So far i have cooked whole chicken, chuck roast, baby back ribs, chicken wings and poppers. When i go over four hours the bottom vent starts to get clogged. I lift the pot off the grill and use a stick to clear the ash.
