That is a fantastic grill. I have the same one. Picked it up at a yard sale for $30.00, 4-5 years ago. It was garage-kept and covered. She even threw in a propane tank. I've had to replace the grill grates, and the flavorizer bars. I've been nursing along the crossover-burner tube, (the little tube that runs across the ends of the 3 burners, and is utilized to ignite the two back burners), but it's finally deteriorated to the point where I just ordered a replacement. The burners are in great shape and it's a serious workhorse.
Our grills look identical, except mine does not have a fold-out table, on the tank side.
